A scarce antique patent expanding brace centre bit manufactured by Samuel SMITH & SONS of Sheffield.
Marked 'S SMITH & SONS SHEFFIELD' to one side of the bit with '9/16' on another.
The adjustable cutter is marked 'R J ANDERSON'S PAT: SEACOMBE ENG'.
We have struggled to find any further information apart from a copy of an advert shown in Tweedale's Directory of Sheffield Tool Manufacturers 1740 - 2018 that includes 'Sole Makers of ANDERSON'S IMPROVED PATENT EXPANDING BRACE CENTRE BIT'.
The hole through the shank of the bit is threaded, please see close-up images.
All parts move freely and tighten securely.
There is some wear to the head of the lower screw, please see images.
47/8 inches (123mm) overall length.
