Over 500k made, so its a common gun. I think $459 is too much given the refinish. You would have trouble getting your money back and while you may not care now, who knows what could happen in a year or 2, so I like to mentally cross that bridge before a purchase.
Things to look out for? Well check the bore, it could have been used with corrosive ammo. Also, make sure the grips are authentic colt for that kind of money. More important yet is the magazine. It should be makred "COLT 32 AUTO". If thats missing, occasionally the repro mags don't work as well as a factory mag. Factory mags are well over $100 and I saw some clean ones sell for $250 on gunbroker.
I think it would be a good gun for $300 BUT they are in demand, and the value of original specimens is not falling any. My advice is to hold out for an original piece. Sometimes spending more is cheaper in the end when the item has a higher value right off the bat. If you are interested, PM me and I will try to find you the good clean original one I was watching on gunbroker for $550. While its more money than $459, you can always get your money back when they're nice. They are one of the better 32 auto designs of all time and were a popular favorite when made. Despite being more expensive than the 32 auto offerings of Remington, Savage, H&R, (even S&W made one for a lil time) they also outsold them handedly which tells you something.
