Evening Ladies and Gents,

Long time lurker here, nice to meet you all!

I scored a rotaform spin fixture (like a harig grind-all) on fleabay. It has a collet fitting with a very short collet that i cant ID: Ive not seen one of this form factor before, and a search of the net didnt dig much up. I was wondering if someone more knowledgeable might have some ideas? Its imperial, having a 7/8" 'pilot' diameter at the rear, major diameter on conical of 1.085"(??) and an OAL of just 1 5/8". Broadly its like a din6343 dead length type, but different dims onviously, and its missing the stepped diameter on the front face, its just flat. Any thoughts or pointers very gratefully received!!

As an aside the fixture is nicely made, but a bit old, so im giving it a strip and rebuild. Let me know if anyone is interested in some pics and build/strip notes, and i'll post. Theres not much data on the web on them, so if anyones got one, memories of using one, or maybe a copy of a manual that would amazing; I love the old quality stuff and its history...

Anyway thanks in advance!
