First, my mistake, all are 1922 dated, the 1924 I mentioned earlier is my NZSMLE Mk III conversion to .22. The 5/22 rifle pictured is the one with the 1925 barrel, matching. All three were .22 Short Mark III that were upgraded to .22 Short Mark IV* with the change in nomenclature (event though besides the "IV*" they are still in factory Mark III form). All are different obviously, love my early .22's. In fact just purchased a new to me .22 Short Mk IV*, coming soon.
