Cheap MM jailbird- $150 shipped w multiple base rings

For sale is a mature metal jailbird.

The original diameter is 1.375", it has been ground down a tiny bit to make it 1.40" It was re-smoothed to 1500 sandpaper and has no rough edges. Unfortunately this was still a little too small, so it is for sale. This is not original condition, but it is in excellent condition, and does not affect comfort or security at all (so long as the size fits you) and is priced as such.

So- current dimensions
1.40" diameter
2.5" length
It will be sold without the security screws, but it is set up for them. I can include a non security working thumb tack screw if you want so it can be used. Security screws and keys are available from mature metal regardless of the cage
Additionally it will come with multiple base rings- just looking to get rid of them.
DOUBLE base ring- OVAL - 1.85" across 1.65" tall
single base ring- OVAL - 2.25" across, 1.98" tall
