Colt MkIV Barrel

[Tbolt]

Hi All

I am trying to find out the value of a used Colt MkIV Series 70 barrel.
I have looked in the EE and found nothing to compare it to, so it was suggested to me that I try here.

It is a .45ACP 5" barrel, with the barrel link and the link pin

FWIW, I bought a Colt Super .38 barrel today, in excellent condition, for $25.
