Thank you for posting my pictures!
For some reason, I have been only able to do the links….
I also found this picture of the Rigby takedown that has numbers 1 and 0 in the serial number on the trigger guard. As you can see, the font is identical to the 1 and 0 on my rifle’s trigger guard.
Also, the gold filled “safe” marking on the safety is identical to mine as well.
