Can you pleasure us with an image of the water table & standing breech? The frame looks to be non-Suhl but it is possible that an in the white longarm was sourced from Belgium and completed in Suhl. Toplever with the Daly example is very similar. I don't think the M on the underside of the right tube to be for McComas as there were mechanics in Suhl that used the letter. Are there initials on the tube opposite the M stamp? I have strong reservations that McComas finished the sporting weapon.

Kind Regards,
