Yes, it does work on all the Hornady series of trimmers (camlock, deluxe, etc). I can take a picture of it attached to the shaft of Hornady trimmer later today if you like.
I've sold a lot of the trimmer adapters for all three major trimmers companies, RCBS, Forster, and Hornady... I haven't had one complaint nor have I had one returned yet :-)
The Hornady and Forster adapters are very similar in appearance and same price, that's why I placed them in the same ad together.
the Hornady will not fit the Forster trimmers though, nor will the Forster fit the Hornady trimmers... that's why I ask folks to specify which trimmer brand they have.
