Police Positive Special
The Colt Police Positive Special was an iterative improvement of Colt's earlier Police Positive model, the only differences being a slightly lengthened cylinder and elongated and strengthened frame to allow the chambering of the longer, more powerful .32-20 Winchester and .38 Special cartridges.
 
This one is in .38spl and has maintained about 75% of its original bluing!  Bore and timing are in good shape and its a wonderful addition to a collection!   Comes AS IS no paperwork or box!
