Well, now it gets more interesting.
C or F Series 2nd Generation? Special Edition? 3rd Generation?
From the same source, a basic 100% 2nd Gen C series is valued at $725 (3rd Model only one made); a prototype, identified by serial number, is $1,350. Special Editions vary considerably, up to $8,500 or perhaps even more.
A basic F Series is $650 to $700 depending on 1st, 2nd or 3rd Model. There were also Special Editions in the F Series but they only bring about $1,200.
Third Generation Dragoons bring $600 - $650, with Special Editions near $1,000.
The same questions and ranges of values apply the 1851 Navy as well. It has more variations in the Special Editions. The basic 2nd Gen could be worth from $650 to $1500, with the Special Editions bringing the same prices as the Dragoons.
Need a lot more information to be any more specific. Like pictures, serial numbers, etc.
