The LB&S ads on Gunbroker include a listing for a Charles Daly Diamond Grade.
https://www.gunbroker.com/item/963215066This is one of only two or three reserve auctions I can remember from them.
I found it interesting for a couple of reasons. I don't particularly recognize the damascus pattern, but am not an expert on them. It actually looks similar to the few inhouse Parker made Laminated barrels (I have one of them).
The second thing is that you can just see part of the Linder stamp on the barrels. Other than the serial numbers, there seem to be no significant markings on the gun. Their writup indicates that Lefever at the time was their US contractor, and they thought the gun likely was built in Germany but finished by Lefever.
Could this be the case? I had never in my limited experience heard of this connection. I will have to say that even before I read it, I immediately thought of high grade Lefever engraving when I saw the bottom metal. The upper engraving looks normal but the bottom has a combination of birds, animals and dogs that looks very much like theirs or a high grade Ithaca.
Any comments on this? The pictures in the listing are awful, but the link to the high rez photos are revealing.
