The Colt, if complete with box and papers should go upwards of $750. An average Colt with out the box and papers is going for around $600. in this area. I did see an exceptionally clean (like new) complete with box and papers go for $1250.
The Model 41 can also go from one extreme to another. An average gun can sell for around $500, while an extra clean one with box and papers may go for well over $1000.
Keep in mind, asking how much the guns are worth is kinda like asking, "How much corn can I get from my corn patch?" It is awful hard to give a good estimate until I have seen the corn patch.
