Gunter,
You have a real beauty there, awesome. I agree the contrast on your piece looks really nice.

I'd love to hear if anyone has ever seen a "R" & "L" stamped on the frame like that (on any gun). With no other identification marks on the frame... I don't know. However, often times the simplest explination is the right explination...

Raimey, based on your response to Xausa, I'd guess you've never seen anything like this?
