Jeeze, I should charge ya $50 just for all that digging I had to do!
I know I have at least two more somewhere, but the three I found are 7mm, 7.7mm, and a 8.5mm that was welded on, filed down and stamped 8.2mm, and bent to the left. Don't ask, I have no idea.
Also found a complete and like new rear sight, and a stripped bolt body I forgot I had.
9mm seems to be the one everyone wants, so I'm going to take these three over to my welder buddy and have him run a bead on top and dress em all down to 9's or 9.5's. Give me a week or two, I have to catch him between jobs, and I'll get one out to you. PM me a mailing addy!
On my parts gun M39 PU sniper, the rear iron sight was buggered, so I filed out a U notch to clean up the V, and brazed a piece of brass brazing rod on top of the front sight. Lowering the V into the U, and adding the brass bead on top, put it dead on at 50yrds.
