Thanks fellas.
The remaining marks Mike notes are identical to those on my 10. One barrel, however, bears one 4-digit number and the other, five. Ross, the pictures which the firm had posted are now removed. Don't have other means of taking/sending photos. I appreciate the offer a lot.
What I've read to date indicates that Schoveling Daly and Gales was a prominent importer. Also, VL&D is sometimes mentioned. Would speculate there's no way of telling which source - or another source - sold a given gun here in the U.S.
Were these guns identical to any model made by and marked as a Sauer?
Thanks again.
