Peter:

Now that I am looking for the "Sl" mark it seems to surface quite often. The longarm of question with the "Sl" mark is a double rifle in 7X57mm proved in March of 1925 and is the subject of an article in "DGJ" Spring 2000, Vol. 11, Issue 1, page 144. It is a O/U double rifle with the stamp of O. Geyger's of Berlin. I'm relatively sure it was sourced from Suhl and maybe from one of the Schulers. Others longarms in the article have Boehler tubes and I expect to see Roechling and others. Not to degrade the Liege based "Sl" by any means, but would it have sold as well in Berlin or do you think it was the maker or firearms merchant that made the difference and not the tube type? If "Sl" is not for the Liege conglomerate, there are very, very few German options.

Kind Regards,

Raimey
