12/10/19 - This is a rare Astra 600 that was part of a Portuguese Navy contract following WWII. All of these pistols are marked M.R.P. for Marina Republic of Portugal, and fall in the serial range of 44501-45300. There were only 800 produced! All matching and original, with 98-99% original blue but some minor oxidation to the finish. Terrific bore and nice, original grips. It does have a tiny import mark on the bottom of the butt in the mag well, which almost looks like a ding.
