What's it worth, cocker barrel edition

[coyote]

So I have been pulling nuggets out of the aluminum mine. There are things I have a good grasp on value wise, and stuff I don't. These barrels are all cocker threaded.

From the right the Ultralight is 16, the Lucky is 15, left of that are 14s, then 12s, the bull is a 9.

Input as always is appreciated.

Oh oh oh!!!

Gold CP! I'd be interested in that.

That's a lot of ohs. Charge him out the ass for it!

I'd be interested in the dust red freak tip. Sorry no help on prices though.

if that is a threaded otp barrel, i have inserts for them but no barrel if someone is looking for both.

I'd be interested in the OTP barrel for a project I have.

Is that a stainless or aluminum back on the 14" Dye UL?
The CP one piece immediately to the left of it has a brand new retail price of $30, so that gives something of a starting point for figuring that one out.
Any idea of the bore diameters on any of them? So far as I understand, anything Dye not marked otherwise should be presumed to be .688.

Stainless, it's a Boomstick.
