It sure is a lot easier to come up with theories on what a box code means when there is just a little bit of data.
First, Thanks to all of you who contributed information. What they prove, as usual is that the Fiocchi codes are a lot more complicated than I originally thought.
I have built an Excel list of all the Fiocchi codes I have and those from the Forum. There are some things that show up.
The basic Box number is usually a 7 digit code, with or without the 4 digit lot number on the end. These last 4 digits may have been added at some time as the box code evolved.
I can’t figure out what the first digit is, perhaps a machine line or whatever but it doesn’t seem to relate to a specific caliber.
The second digit could and probably is the year. I have two boxes with dated headstamps where the ammunition is dated and the date on the casehead matches the second digit. There are a number of other cases where there is date information associated with the box, and it is consistent with the second digit being the year.
Digits 3 & 4 are probably the month for the more recent cartridges. The numbers vary between 01 and 12 across the sample. The earlier style boxes seem to have a number in the 30s in these two positions and I have no idea what it may be.
Digits 5 & 6 were reported to me as the day of the month, but this is unlikely. In the sample below they are almost entirely low numbers. It is statistically very unlikely that we would have captured this many boxes loaded in the first 10 days of the month. Of course 00 isn’t a day, but it is interesting that there are also no numbers above 27 below.
I am satisfied that the last 5 digits are some other sort of identification.
The H prefix on the ammunition made in Hungary also makes sense. It is a typical Fiocchi code with an H prefix for Hungary.
We have also documented three 10 digit codes used on Italian made ammo which appear to use the following format as dArtagnan suggested:
Digits 1 & 2 = year
Digits 3, 4 & 5 = Julian Date
Digits 6-10 = five digit lot number
This conclusion is based on a small number of samples
Also as dArtagnan, suggested, the Fiocchi USA ammo probably uses the following format:
Digits 1 & 2 =Month
Digit 5 = Year
Digits 6-10 = Lot
Again there are only three data points so the information is pretty slim.
In fact, the 6 examples available all fit either the Julian date model or the Fiocchi USA model so we need a lot more data in both cases. Still, it is a start.
I am still very interested in any information on Fiocchi (or pre-1946 DWM) box codes. any help is appreciated.
If you are interested in the actual data, send me an email and I can send either the excel spreadsheet or a word document. The word document does not contain all the information of the spreadsheet.
