How much is a old black powder only 45 cal long barrel pistol worth?
No published sn data
yes
I just bought one for $225.00 (12/14/07) in good condition (for an 85 year old pistol) with an after market magazine instead of the OEM. I have seen them on gun sale web sites for as much as $500. There are some tricks to disassemble and reassemble the pistol and to remove and install the handgrips. Damaged handgrips are a sign that the previous owner applied force instead of intelligence.
Unknown.
50-500 USD or so
