A post war Bolo stock looks the same as for a standard grip with a 5.5" barrel but the internal milling is different, for the smaller grip and the shorter barrel, A standard C96 will not fit in one. It may or may not have a serial number on the iron and the Mauser logo pressed into the side.
There are a variety of leather holsters. The most common being the Asian type with a flap and side pouches. These are also the one you will see the most reproductions of.
