Listed is a Lathe Tool Post Holder, measuring 2.5" x 2.5" x 1".  It is stamped with the initials, "JFH".  There are no other markings.  It likely was custom-made.

Shipment in the US is through USPS Standard Mail.  I may use recycled boxes and packaging in order to be more eco-friendly.

I will ship internationally, if eligible, through eBay's International Shipping Program.

Thanks for looking!  If any questions, please let me know.
