Japanese 37x165Rmm artillery cartridge

I went to a NJ Military Vehicle Association show and found Mr.Randall Walti (exhibit 1) in possession of this round which I hoaxed from his hands by using multiple $20 bills. None of my Jap ammo has any markings. So I got this one just to have one with something written on it. It measures about 37x166mm rimmed with a solid AP projectile. What is it?
By the way, Randi is DRIVING to SLICS, with present day gas prices it is like shooting 1inch Gatling gun with original ammo for a week. Wish him good luck. I myself shall be in Gyrojet’s 2nd most beloved place (after St.Louis), and I’ll be thinking of all of you in sunny Las Vegas.

Vlad, come to Germany next week and you will enter a new dimension of fuel prices.

Randy is a Very fine fellow and long time artillery collector with great taste. The last thing I sold him was a WW1 German railroad gun projectile. He had to bring a truck to get it.

Americans have little idea about gas prices. When I moved to Denmark in 1969 I filled up my Thunderbird before putting it on the ship. Gas cost .39 CENTS a gal. My first gas purchase in Denmark was in the $5 per gal. range 3 weeks later. I cut back on my driving and learned to ride a bus. I could not bring myself to join the heard of bicycle riders.

As per today the US gallon is 9.27 US $ here in Germany.

Here in the UK it’s $8,26 per US gallon for unleaded, more for diesel … with no sign of a slowdown in the increases at the moment.

I’ve suddenly developed a very light right foot and try never to actually come to a halt once I’ve started a journey.

Happy collecting, Peter

I feel for you fellows and us. America’s prosperity has been based upon cheap gas and good roads. Both are coming to an end. Getting back to ammo- I used to buy one inch Gatlings for $25 and turned down many shells which today sell for $1000 and more when they were 50 and 100. I would gladly buy back any item which I sold on my first auction 20+ years ago at 5 times the price and could resell the same at double that. I guess that 39 cent gas won’t be coming back soon.

37 x 165R used in L46 Type 94 anti-tank gun, Type 98 tank gun, and also installed in the Ki-45-KAIb aircraft (manually loaded).
Fired an AP shot weighing 700 grams at 700 m/s.

Any of you can tell me how many liters is a gallon?

Today, one liter of diesel costs 1.35 € in Spain

Thanks to Zapatero and his “socialism”… No coments…

In the UK a gallon is 4.54 litres or 8 pints. The gallon in the US is smaller.

1 US gallon = 3.78541178 liter

The case is dated May of 1941(Showa Ju roku nen) w/ Nagoya arsenal mark
The primer is dated Apr 1940 (Showa Ju go nen) w/ 1st Tokyo Arsenal mark “star w/ circle in the center”. The kanji at 9 o’clock above the star I believe it to be associated with the Kokura arsenal. As I have seen it on guns and swords made after early 1900’s up to 1945 that have Kokura marks.
You probably already knew this…

The primer may not be original to this case. The spanner holes are very abused which indicate that it has been removed with effort. Two arsenal marks on the same primer ? Interesting. Very little - nearly nothing is known about Japanese recovery and reloading of ammunition. If the second mark is actually an arsenal mark it might imply that they actually made some effort at this.

What do you think the “F” means ?

I can’t say for sure about markings on shell casings but multiple arsenal marks on firearms and swords and other edged weapons are somewhat common. I suspect the same policies were not limited to small arms. Inspectors marks associated with the Kokura and other arsenals are found on or associated with private company contractors. This mark may indicate the contractor overseen by a Tokyo and or Kokura inspector.
Your guess is a good as mine on the “F” . Why a non Japanese stamp? There are 2 other inspectors marks and they are kanji, on the case. this is the only non-Japanese mark other than the #5 -4. I looked at the F from different angles thinking it might be kanji but it is clearly an “F”. Perhaps an ordinance mark by US or Allied forces indicating capture and deactivation? The US did grind the “mum” off the receivers of captured Japanese rifles?

I don’t think the occasional use in Japan of letters of the Latin alphabet for symbolic purposes is particularly remarkable. We English speakers write “LB” for “pound” and yet “pound” has neither an L nor a B. Russian speakers write “No.” for “number” and don’t have a letter resembling N in their alphabet. It’s just the way we humans are. Jack

You are absolutely correct. It could indicate a lot#?.. In the late 1800’s they adopted the Gregorian dating system but continued to use the nengo dating system and as indicated on this case combined arabic numerals with the centuries old nengo system. Dates are still found in both systems in everyday use in Japan.

The small kanji at 9 o’clock on the case is “Na” or “Mei” = meaning “signature”. It is a general inspection or acceptance frequently found on firearms from the Nagoya Arsenal. The other one I believe is the Tokyo Explosives Factory mark.

Sportclay: I wish I could help you on this, but I have little background on artillery markings generally and Japanese ones are hopeless to me. I did look again at the pic after reading your remarks and think I see that the bottom four groups of markings do represent Nagoya-5-16-Showa, or am I kidding myself? I know a little about small arms markings but this stuff is in a league of its own. Jack

I collected Japanese swords for nearly 30 years. Out of necessity I learned to read Japanese and can translate most Japanese characters/inscriptions. However the inspection marks are to me, only kanji, as to what they represent in this particular context is speculation derived from looking at a lot of Japanese weapons and having a fairly good library which includes some books on more modern Japanese weapons. Several of these have fairly extensive proof listings. Over the years people have brought all manner of Japanese “things” to me for “translation”.
These types of markings are new to me as I have never looked at a Japanese artillery shell. I will pay more attention to them in the future when I see them at gun shows. My interests in cartridges is mainly aimed at British sporting and military rounds. With a growing interest in Metric sporting. I own several British and Continental double rifles and single shots. Shooting them and reloading for them keeps my interest growing.

The “F” is a common Japanese marking on artillery cases. No proof to my knowledge (yet) as to its meaning. Opinions, yes.

I was asked by municion.org to take side shots of the entire thing, and, whilst doing that, I pulled the projectile only to find that it was “bottomless”. So, how did it look originally? That hollow space was filled with HE (I assume). Does it make it API?
