I have one looking to sell and am wondering what they are worth? Mine is in good to very condition with box two magazines and wood grips. Only serial number I can find is tal07xx. It has adjustable sights. It has been carried more than shot. Thanks in advance. I will get pics up on Thursday. This one has square trigger guard and the lanyard and the rounded back strap.

Thanks to those who responded already and for setting me straight on the serial number. Eyes are getting weak!

The serial prefix "TAL" was used around 1986-87, the fourth digit is a zero, not the letter O....TALO models did not yet exist when the model 639 was made. They are one of the most sought after 39 series full size, and sell very regularly between four and five hundred, depending on condition and accesories. Please post some pictures....there are a few different configurations of this model, including square or round trigger guard, lanyard loop backstrap or flat bottom, short wide extractor or short thin extractor, in addition to fixed and adjustable sights.....most of the ones I have personally seen that have the short wide extractor also had factory adjustable sights....

Would love to see some pics also.
