I'm looking for info about a combination gun I recently acquired. It is a Tikka over O/U, marked 12-76/.222, and has the name Armistad Arms(Armory?) on the left side of the barrel, in gold letters. Found ref to LSA55's from Ithaca, but this gun only says Tikka and the name above, although otherwise it matches all pic's. Ser # in 60K range. Wondering if made in Finland or elsewhere, and about when, and any other opinion or pertinent info.
