rigbymauser,

I think you covered everything in your post. I just depends on which order you put them in.

Re the Jeffrey, it is probably the calibre that makes it more valuable.

Factors affecting value are (in NO particular order):
name
condition,
finish
amount of engraving or lack of
wood - fancy or otherwise
caliber
Sidelock/Boxlock
Hammer / Hammerless
Ejector/Extractor
Type of wood
cased / uncased
attractiveness of gun
Balance, Fell, Fit
Bore condition
Barrel Length
Originality
+ probably a whole lot more.

It is hard to put into words what affects value more - all or some of the above
factor into the equation at some point. You also get particular
markets (ie The US) that have particular bents (Good Wood, Engraving,
NAMES and condition !!!)

Hope this helps
