I would guess you're up 3-400%
In other words you're saying with no box or tools I could post this thing for sale and ask $2k??? Is that due to the scarcity of the 4" version? All I can find on GB is 6" versions and they're all over the place price wise.
Standard Catalog puts this one around 1956 sometime (real close to a birth year gun for me!). From the looks of the recoil shield it hasn't been shot too much. It looks like the pitting on the back of the frame has been touched up with some cold blue......
Would you say pitting? Or was it used as a hammer?
