See my previous thread listed below where in it was identified by a Hobby-Machinist member who also sourced a great chart of Logan collets. It was made by Porst Bros of Chicago.
This collet is surplus to my shop, which I am downsizing, and much to good to chuck it into the trash.
Free for USPS snail mail postage, which should not be more than a few bucks. Post or send me your address, or call me at (636)797-4203, but speak slowly and repeat your phone number as I have lost much of my hearing.
Thank you, Karl Schmitt "Spitfire"
