Here is a very nice THREADLESS CD 729 Specimen plus a bonus piece.. also a CD 729 specimen with missing pieces, but will stand on it's own.

This first photo is only the MAIN one. It has a few missing chunks out of the rear and some fractures. When viewed from the front, it looks complete with a fracture.

The second photo shows the rear with the missing chunks, but also looks pretty good.

The third photo shows the first complete piece with the specimen on it's side

The fourth photo shows the first complete piece with the specimen standing up.

The book from 2018 says the CD 729 at 600 to 700. I'm asking $125 for both.plus shipping.
