rear carbine peep sight code

I have a carbine peep sight with the code BR (who made this peep ?) and what would be the correct base for this peep sight ?

If original, it was made for Rock-Ola by

Jasper Blackburn Co.
St. Louis, Mo

They made both the leaf and the base marked BR

Thanks for the information, the peep is original as I have had it for a number of years, it is a medium color of parkerization

I have one in my parts box too, but somewhere in the past it was put on the wrong base.
I've been looking for a base a long time.
Oh well, 1/2 of a good sight anyway.

I have a photo of my BR peep sight on the carbine forum of jouster if you want to view it, can't post photos here.



Here they are.

Hello
I am having trouble finding out who the MFG of my m-1 was.
Can't find any MFG stamp any where on the gun.
Any help would be appreciated.

Some commercials have them stamped on the side. Take it out of the stock and look for a small ERMA on the left side of the receiver. Where is the serial number stamped?
