Value is too difficult to be accurate without seeing the gun. Condition which includes the amount of original finish and original configuration will determine value. Recommend taking it to a gun shop for appraisal.
If data has been published, by serial number or features.
there are too many numbers in the serial number of the first pistol. On the second pistol is the prefix 'CP' or just 'C' ????
1-40,9061
Check the receiver and barrel
Buy one of the books that has published serial numbers for that particular pistol.
You can look up serial numbers at Proofhouse.com
The only way to find out how old a Bretta automatic pistol with the serial number 605222 is to call the company. There is not a listing for Bretta's by serial numbers online.
None of the existing ORIGINAL guns have serial numbers.
Might go up to 150 or so for a really old one in superb condition with original box.
serial numbers are of no value without the makers name, model of pistol, caliber and overall condition.....................
