This is one that I was going to hang on to but I'm narrowing down the souvenirs from the film, and this one can go to someone who likes it not only for the paintjob and quality liner, but also the fact that this is a piece that was used in the opening scenes of Reveille by Unteroffizier Ewald as pictured, and is part of Film History.
This is a converted Finnish M40/55 with a size 64 shell and 57 liner. If you want me to write something authenticating this, I can do that, just email me.
