1918/1920 Value?
 

I recently bought a 1918/1920 DWM.it has been refinished at sometime{all small parts blue}.No import marks, matching #s,grips appear orig. 2 un-numbered wood bottom mags.one has a +, 1915 dated holster{no takedown tool} and the set of Sept.20,1945 capture papers matched to serial # on pistol. Grooves in barrel a little rough.Also, forestrap is unit marked 9/JR 1061. I paid $650 for the rig. Years ago my father who was born in 1919 gave me a 1918/1920 DWM. Unfortunately, I sold it. Having matured and growing nostalgic, I decided to replace it in memory of the one I sold. As the commercial says" memories are priceless". On a true value level what is the rig worth? Any info. helpful. Thanks,Dan
