Raimey,
You are like a walking encyclopedia of guns. I wish I could hire you to follow me around all day and tell me what things actually are that I see! Like a faithful golden retriever, but with an IQ of 180. You're remarkable!
Anyway, I couldn't find any examples of the E. Schmidt & Habermann Model 501, Roux-Drilling online. I'll look in my copy of "the drilling" to see if I can find any more information out.
I did find this link to a VERY badly treated drilling that has much in common.
http://forums.nitroexpress.com/showflat....amp;Search=trueIn that dialogue, they said it was a Meffert drilling. The receiver on the gun we are discussing now is identical as to the position of cocking indicators, etc.
What I find very distinctive is that both guns I've discussed AND the gun at the link above all have that very peculiar method of joining the receiver and the wood stock that I don't see in other drilling examples.
Do you believe that the gun we are discussing, the gun you addressed for me in the other thread, and the gun at the link above attributed to Meffert are all from the same manufacturer?
Do you believe the engraving on both of my guns is from the same engraver? (it seems very, very similar in style and pattern) How did you come to believe Franz Keller was the engraver?
Lastly (and I know I've asked a lot of questions of you), do you believe this gun is desireable/collectible if it is currently in 95%+ original condition? Is it worth $2000, or $4000, or other?
Raimey, you and the rest of the contributors on this forum are the best. I hope to reward you with liquor or cigars should we ever meet in person.
