Question: KING reflector ramp sight/base

[digi-shots]

I have two KING stamped bases.. one has a sight blade, the other doesn’t. Both are curved underneath and go directly on a barrel.

I think the smaller one is for a Colt Woodsman and has the letter A underneath.

The larger has a sight blade and has a number 8 underneath.

I’d like to list these for sale but not sure of their current value and what they fit.

Thanks!
