Can you tell me what a colt commando serial #11859 might be worth

Your Colt was made in 1942. I forgot which branch, but I believe it was USN.

A 1903 Hammerless .32, I assume? Yours was made in 1920.

This is an easy answer. You can ask Colt directly through a special webpage by entering your serial number.

Check at the parts store or dealer and see if you can get parts for it. if you can then it might be if you can do the work on it yourself, and depending what is wrong with it. Before you buy I would at least check for spark and fuel. Good luck

It is 24 years old and you might have trouble locating parts if you need to repair it. I would tell you for the right price any car can be a deal but you may spend more then it's worth if you are walking instead of driving.
