NO No, if you can't read the number.
You need to call Colt to find out.
Which model?
97 years old
If you have a Gov. Model .45 (1911) with the serial number 350268, it was mfg by Colt, and made somewhere between May-Oct, 24, 1918. It fell in the serial number range 290,000 to 450,000
you might want to check serial number again. don't believe there is a 'c' in the middle of the serial number..................
@ 1974
50-700 usd
100-800 usd
300-500 USD
Round $1000, but prices fluctuate a lot from place to place, model to model. I've heard that standard blued models can be brought at $500, but I haven't seen any. It depends what you're looking for.
