No1 Mk3* HB Rear Sight

[tbonesmith]

Not too long ago I got a reamed for H barrel, rear sight base from "The Gunsmiths" at Sefton, NSW for $20, I'm pretty sure they've got a pile of them, you should give them a call or email, they've got a good web site too Gunshop - New and Used Guns , Pistols and Rifles for sale, Custom Gunsmithing , Firearms and Accessory , Dealer for over 30 years - Sydney NSW Australia could be that easy!
