This one of those items I have had my suspicions about for years.....
why in time of war produce two styles of cans that do the same thing?
And you would have to have both styles on each and every thank!
you would need these inside and the style with the latch on them for the 17 mount on top of the turret.
I am thinking these may be prewar as quantities are less,
I have owned three of them over the years and all of them were in primer
not painted white,
the latch system when compared to the standard ammo can is awkward to say the least!
The large rings would lend them selves to a carry strap which would suggest the original intent
was for infantry use,
I really think this is one of those items that was produced in limited numbers either in the 1930's
or at the beginning of the war and sat in a warehouse some where after being rejected in favor of the standard can,
I have yet to see one that shows any sign of use.
I have a feeling some enterprising surplus merchant started painting the cans white and selling them as ones used in tanks,
hence the rarity, and may also be why I have had three mint new ones all of them in primer in the past 10 years.
What does Dolf's books have to say on this?
