Very Rare Chaplin's Patent Standard Tool Co. 12 Inch Combination Center Square from the 1880’s

Originally, these squares had 4, 5 & 6 inch base's with 6, 9 & 12 inch rules. This is a 6 inch base but is missing the original 12 inch rule.

It is a great antique piece in great original condition.

I come to Salt Lake often if that helps with travel.

Please call or text with any questions.
