How do you get your name on that bid list?
I have a Police Positive Special manufactured in 1927 (if memory serves me correctly). I couldn't tell you the value as it's been in the family for well over 60 years and I wouldn't sell under any circumstances. When I got it it was pretty well rusted so I had reblued. I take it out every once in a while and run some standard 38's thru it. It's still accurate and the trigger is excellent.
I would think $150 would be a real bargain for the one listed.
