I recently looked over a sidelock that was sold by New England Arms of Kittery Point, Maine, (which is what was engraved on the barrels). The gun looks to me like it possibly was made by Arrieta. The gun appears to be well made, and based on my one visit to NE Arms, I'm sure it wasn't cheap. Since they are out of business, my only hope of getting any information is that someone on this board can provide it. Anyone out there know who made the gun, what price it sold for, if there was more than one model/grade offered, etc. I would greatly appreciate any info. Thanks in advance.
