Well, my wind gauge has a bar across the front with a screw in the middle. It does have the left and right under the bar. Here are the SN numbers when I finally got the nerve to take it apart and find them; SN is 279901, Trigger housing is D28290-12 SA, Hammer is C46008-5 SA, Bolt is D28287-12 SA W9B, Operating rod is D35382-1 SA, Receiver is D28291-9 SA with RE 1 stamped over top of number and "&" near the end of the number. Barrel is D35448-7 Rep-16. I will try and get some pictures on here as soon as I figure out how to do so. Thanks for the help.

Nope, it is a S.A. - S.H.M. What is a PM? If that is personal email it is
boomersusan@msn.com. I will dissemble and take some pictures. Finally got the nerve, and after watching several videos, gave it a try. Had a little problem with the op rod and I at first put in the spring upside down, but finally figured out what I had done wrong and got it back together.
