This old 44 Spl. was found at the Crawfordsville In. gun show this past weekend. The finish is thin & the grips are worn but it locks up tight and functions normal. I thought the 5" barrel was different and didn`t even notice the HPD marking on the backstrap untill I got home. This turns out to be one of 300 prewar 3rd models sent to Wolf & Klar for the Houston Police Dept in 1931. Any Idea of value considering its condition. thanks charlie
