I'm trying to identify and value a percussion doglock pistol I purchased about 40 years ago. Caliber appears to be about .69 smoothbore, has brass fittings holding stock at muzzle with attached, hinged ramrod. Without disassembling, only marking on metal is a stamp at the rear of the barrel, on top, just ahead of the tang. Appears to be gold inlaid. Stamp consists of a crown, some sort of decoration, and two rows of letters. First row appears to be AULU, second row appears to be AGA. There also are some stampings on the stock. Top a crown over a capital R and to the left of that a crown over a capital Z. On the left side of the stock, just above the trigger, are letters that appear to read BVD ARTE. My recollection is that it was Spanish and made in the early 1800s.
Attached (I hope) are photos.
