For sale/wanted (Please be aware of scams) discussion

I’m searching for a mature metal jailbird with an inside diameter between 1 3/8” and 1 1/2”, a base ring size of 2” to 2 1/8” (preferably oval), and a length from 2 1/2” up to 2 3/4”. I’d like it to have a security screw, though that isn’t strictly required.
