It is a nice looking gun.
Though it only carries a small premium over a standard production 3rd model Dragoon, there are only 94 of these Garibaldi 'freaks.' You won't see these appear on the market very often. As soon as you shoot it, the value will be whatever used guns go for (see gunbroker) - probably around the $300-$600 range.
Since they only made so few of them, and it is your intent to shoot, I would recommend selling this one to a collector for $700-$900 and using that money to buy a new/used standard production model (qty 2731) for $300-$600.
A freak Dragoon in 100% condition without box and papers is worth in the neighborhood of $650. Values go down from there. At 98% you're looking at $425.00
Thanks! I was wondering myself.In 1982, Colt produced the Giuseppe Garibaldi Special Edition. The model number is F1740 EGA. This was an 'F' series 3rd Dragoon that had the portraits of Garibaldi and Colt on the cylinder and gold etched panels on the barrel. It was encased in a French fit, red velvet lined case, that had an etched glass top. The serial number range was GCA1000 to GCA1299.
The 'Freak' Dragoon is an 'unfinished' model from a small batch of the Garibaldi edition within the serial number range listed above. As you note, it was stated that the 'freak' dragoon in this thread carries the serial number GCA122xx (I wished that people would just spell out the serial number instead of filling it in with 'X's - in this case, too many 'X's). The finishing of the 'Freak' Dragoon is the same as the Garibaldi edition, except that there is no etching on the cylinder or barrel. The gun did not come with a presentation case.
It is estimated that there are 206+ Garibaldi's and 94 'Freaks.'
