Earliest all plastic shotshell?

Hi all,

I was wondering.
What is the earliest known all plastic shotshell on the market??
I have the Dutch robijn shotshells from NIKA being listed from second half of 1951.

What about others??

I used to have one headstamped wienkoop mulheim ruhr.
But have no idea of it’s age.

Thanks for all help.

Hi Rene,

  1. about all plastic shotshell (base and tube) it is 1945;
    i have a drawing somewhere but it does not show hstp or give the color of plastic.

  2. about half plastic shotshell (plastic base and paper tube) it is 1937
    The hstp is : Patent 16
    I do not know which country it is from.
    I put the drawing here some time ago.
    (No access to my drawings right now )

Polman,

attached pics of some experimental all plastics from Eley-Kynoch from 1933.

Only a small run of these were made - did not go into full commercial production.

Thanks Jim!!

Hi JP,
That patent 16 one I have in my collection. And is also somewhere on the forum, but can’t find it right now.

In September 1949 the Danish business DPI started a production of an all plastic cartrigde
t1bund3


t1top3

It was in production for 3 to 4 years, and there is several variants

Thanks Lars,
I used to have three different bottoms of these.

Armourer, is it 1933 or 1941 these shells ?
there is a patent in 1941 but i did not find one before

Jean,

Definitley 1933 - I got these from the Kynoch factory historian - who also had the relevant paperwork for 1933.

Those pics have appeared in several journals over the years with descriptions.

Jim

Thanks.
But they did not take a patent for it ??
Because it was rather new at this date

JP,

No patent, it was still only experimental at this stage, they were trying out different types of plastic.

Jim

It seems you posted some pictures but it did not work

JP,

No pictures posted intentionaly - my error, I replied using an old email system that automaticaly adds some gif, file advert, which is what you see.

Further to my reply on the 1933 plastic cases, you can see another pic of one from 1933 on page 116 of Bill Harding’s book “Eley Cartridges” This book as you might know is the Bible for Eley cartridges as Bill worked at the Birmingham proof house and also had full access to all the old Eley-Kynoch records.

There is also a reference to these in the “Eley Story” 1828-1978 where it states that they did not go ahead with the plastic shells at that time because " the cost of production would be such as to prevent them being a serious competitor to paper cases".

Thank you very much

Do you know the meaning of 200A and 1204B in the hstp?

JP,

I was told they were code references to the types of plastics they were trying.

Hi Jim, I think the ICI cartridge is mostly described in this patent from 1937 (application filled in 1935). There is also an earlier patent applied in 1932.
