Tony Posted June 1, 2006 Share Posted June 1, 2006 Hello Jim,I don't know, hopefully someone else does.All I could 'guess' at is if Gunmod isn't the manufacturer, then maybe the shell was meant for a gun as opposed to a howitzer.Could 100 FPS be 100 feet per second?There was a case 75mm, model M1917, GUN which was of US manufacture.Tony Link to comment Share on other sites More sharing options...
Jim P Posted June 4, 2006 Author Share Posted June 4, 2006 Thanks Tony,I don't know about the 100 FPS,but 100 Feet Per Second is rubberband gun slow,so I don't think that is it.That popped into my head too.It has been suggested that the 1st one is a 3 inch navy and the other is a 5 inch navy that has been cut down.Jim Link to comment Share on other sites More sharing options...
Tony Posted June 4, 2006 Share Posted June 4, 2006 Jim, How about this explanation for FPS: FPS - Federal Press Steel Company, Milwaukee, made 3, 6 and 7 inch cases. 3 inch sounds about right for your one. May be the 5 inch came from them too. Found it at this site http://home.hetnet.nl/~supersmit/ww1/stamps2.html Tony Link to comment Share on other sites More sharing options...
Jim P Posted June 5, 2006 Author Share Posted June 5, 2006 Thanks alot Tony.I would say that the 3 inch is a lock.The 5 inch is probably going to be a little tougher,because it is completely unmarked.Thanks againJim Link to comment Share on other sites More sharing options...
