Thank you for posting again, Raimey, much appreciated! I would appreciate any insight or information from the markings on the barrels and action.

I must have mis-typed, Raimey. The A. Mulcaz is a combo, 8x57JRS x 20 gauge. It was supposedly changed from the original calibers or gauges into the current configuration sometime around 1990 and not sure the source of the seller's information on that. The forend wood doesn't appear to match the butt stock, so I assume that may have been part of the workover/rebuild.

Thank you to all those who share such valuable information on this forum!
