Since you did not give a serial number or part there of, what I think you have is a Colt Police Positive Special (First Edition) . this has fixed sights and wood, rubber or plastic grips. Mfg. 1907 - 1946. It was the only edition in 32-20.
100% - $495 NIB with all papers
98 - $450
95 - $395
90 - $325
80 - $300
Hope this helps.
And yes, I have a box of original Winchester Super X 32-20 for sale.
