Nice guy, has most Lyman parts.

Thanks Irv, I called Dave and he only has Marbles parts. I did order a Marble's tang sight from him when I talked to him but I would really like to find a new stem for my Lyman. THANKS!

You are right, I have two Win 1906"s one with a Marble, one with a Lyman and was confused.
I was able to get a new

stem from Lyman (some time ago). I would go to the Library and get the name of someone with
responsibility at Lyman (the girl that answers the phone will only look at the catalog), and write them a letter.
In a company like Lyman there are many drawers with stuff no longer cataloged.
If that fails go to Goggle and look up Lyman sights, or sight parts and start digging.
Good luck!

The parts for obsolete Lyman sights have already been bought out.

Thanks for the reply's guys. I guess I'll have to keep looking.
