Watchmaker’s 10MM Pivoting Head Milling Attachment for 10MM Lathe

This lot contains a good, clean early watchmaker’s important and rare 10 MM “Pivoting Head” Milling Attachment for a 10 MM Lathe. The milling attachment is clean, functional and is the hard-to-find, rare 10 MM size. The milling attachment is signed #8. This attachment was found with a Derbyshire Magnus 750 important 10-millimeter lathe. I am going to offer this attachment to the horological community These 10 MM milling attachments are basically impossible to find. I have only owned two in 44 years. The tool is in good, clean, not polished and functional condition. You can go out and find an 8 MM attachment but the 10 millimeter milling attachments are non-existent.
