SUPERB EARLY BRASS TELESCOPING SLIDING RULE - HAT MAKER'S?

SUPERB EARLY BRASS TELESCOPING SLIDING RULE - HAT MAKER'S?

$245.00 USD

Very early rule that 'telescopes' out. Likely mid to late 1700s based on the look and font. Has a different scale on the back side possibly denoting sizes? Very likely a hatter's rule. I have not seen another like it. Exceptional.
