That is an early 1911, and in "excellent" condition, I would guess between 2500 and 3000 dollars. This would be with all original parts, original blueing, etc. This is of course if you can fine a collector to buy it. These Colts are becoming increasingly rare in excellent condition. In my modest humble opinion of course, I would hold on to it. Look at what SAA are going for these days in those years! Not very many people have the fore-thought to realize that a 100 year old Colt, no matter what configuration, is still a 100 year old Colt! This is a prize to be treasured!
