An elderly gentleman (80) has this gun and would like to know its dob and a value of some kind. He may be interested in the future in putting it up for sale as he could use the money and no longer desires the gun. This is a 6 inch blued with black plastic or hard rubber grips, gun is in fairly nice shape with some very fine surface rust on the top strap and in the yoke area. The rust would probably mostly come off with some work but its not my gun to do. The barrel has a little blue wear mostly at the muzzle. All in all in nice shape. Serial number is 187xx. I will take some pictures tomorrow and try to get them to post. I'm a S&W guy and do not know anything about Colt model numbers etc. Thank you for any and all help with this gun. He is sure it's worth a lot of money but I do not know. Maybe you guys could help me?
