I tend to like early cartridge rifles, in obsolete calibers!

Given the choice between two otherwise unknown examples of the same caliber/type/finish/condition, if it were a gift and I were to be shooting it I'd take the modern piece built with modern materials.

When looking at individal examples, I look at the big picture. Action type, caliber, condition, budget...

For instance, I like the look and feel of a back or island action JonesUL type hammer rifle. Although there are some amazing examples of relatively recent modern rifles built on that pattern, the price..!

Also I do go for the historical importance, note the pinfire rifles I own and shoot -- they're quite rare, and the ones I have are nice examples of period high grade sporting rifles. From time to time I'll ponder the finish wear patterns, the nicks and dings, and wonder where they've been and how the world has changed around them over the past century and a half.

So it's subjective.
Put two as-new Holland and Holland 500-450 best sidelock rifles in front of me, both of essentially identical style and trim, ask me to take the one I'd take as a gift - you'll see me take the one that was built with modern materials.

It is not likely that I will be stuffing one in my safe any time soon though...
