$250 for any Baby Browning in working condition is "buy." Pretty much eh examples push $500 these days. If you can clean up the metal on the version you have IDed and the grips are decent, well, I'd buy it. Obviously, engraved and fancied up Baby's go for a bunch more. Original soft cases add a few more dollars to value.

ps - I own a nice Baby plus soft case in my collection.
