Hello Guys

I'm after a rear sight base for a Model B 250 Savage. The original is a ring base with a dovetail for one fixed blade and two folding - it sits right ahead of the reinforce.

I cannot locate the appropriate base,it is 18 mm ID and 27 mm long. The Recknagel (or NECG on the US)one (part 16510-018) is way to long. Graeme Spraggon, the Recknagel agent for Aussie is out of ideas.

Any ideas on who else to try ??

Thanks
