Thread and Diameter Rem RB Screw

[TCLouis]

Anyone out there know the diameter and thread for the pin retaining plate on a #1 Remington Rolling Block?

Thought this guy listed the size but didn't see it. I can't get to my thread pitch guage and RB for a week. If you don't have it by then, I'll measure one up. The ASSRA forum guys might know off hand...

The one in my No. 5 is 12-28, have mine apart right now and checked it in my thread checker; unless it's a foreign made one it should be the same. Wouldn't think they'd change it at Remington between the 1 and 5 actions, but don't know for sure.

My #1 round top - 11mm belgian barrel and US butt plate is also 12-28x 1/4"
