Hi Bob,The pin pictured is for a 1910 Maxim…..is that what you are after? Or for an MG08 or some other Maxim? You didn't specify.
I appreciate you taking the time to respond to my post, your knowledge of MG's is second to none.An 09/21 is a Russian Maxim, just slightly modified for use by the Finns. Any of the rear mount pins for the Russian 1910s or the Finn manufactured Maxims wil fit the traverse clamp and the rear mount. it is possible someone is making repros of the rear mount pin, but I have not seen one so far. Front mount pins for use with the shield on the Sokolov mounts are being made.
