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

I picked this up last week from another forum member, but I got my measurements wrong and it’s not the right fit. If you need one, take a look. The cage measures 2” in length with a 1 3/8” diameter and a 1/2” gap. It comes with oval rings sized at 1 7/8” and 1 3/4”, along with a security screw, one key for the lock, two separate locks (each with its own key), and a velvet pouch. I’m hoping to get back around $300 from what I paid, so reasonable offers are welcome.

This device catches my eye. Is it still available?
