The Gun and Carrier reside in Ohio, USA. The National Forge and Ordnance Co (now just
National Forge Co ) has gone bankrupt, and been absorbed by another company.
Here is a picture of a similar gun in a Museum/collection in Australia.
And its apparent limber. We believe this because the lunette and Surge Brake assembly are identical to our guns. And it appears to be hooked to the gun.
I am uploading some
more pictures of the gun beside a US M3 37mm gun for comparison.
There should also be a picture of the brass plaque on the breech shield. If anyone recognizes it, we would appreciate the info. Any information will be appreciated (i.e. actual use, numbers purchased, wartime photographs, guns still around). And thanks for the response so far.
