sageman,
You are a lucky man, If you browning has the gold line and in mint condition its worth 1,950 If its the renaissance mod. its worth 2,350.
If it the plain mod. Cased with the three weights the value would be
about 850,00 I used to have one back in the 60s and like an idiot i sold it. In my opinion its probably the finnest target pistol ever made. It has the dry fire mechanism and the accuracy is great. It will only increase in value as time goes on. Hope this helps..........Joe..........
