I hope you resist any temptation to sell the rear sight. It now belongs where it is, as what it is - part of the arm's own unique history. It is no longer suitable for use on a collector carbine, unless - heaven forbid - someone planned to weld-up the missing metal and re-machine it. In an obscure way, it even shows WHY the sights are now so rare - they were used up a long time ago by the surplus market. Just my unsolicited $.02. Good luck, and enjoy your shooting!

Dick, I completely agree and am not a big fan of parts restorations either and it will remain as it was meant to be.  It will remain as is.  As for my loads I'll stick between 150-180 gr bullets which I have in bulk already.
