Heres my Spanish M1,( M1965) which I believe was used by airborne and Marines
( please correct me ,if I'm wrong)
The shell is a standard WW2 front seam,US M1,but the liner has markings which,I am yet to understand.
Could anyone let me know the manafacturers of this type of liner,this would be great for my research.
Enjoy,and any comments would be greatly appreciated
