Stanley Architect’s rules (Nos. 53 ½ & 86 ½) are distinctive for having beveled segments on their inner surfaces. This was to put the included architect’s scales close to the surface being scaled. This example has the usual scales (1/8, ¼, 3/8, & ½” per foot), as well as usual gradations of 8ths, 10ths, 12ths, and 16ths of inches on other scales. This rule, however, also has edge scales with inches, 10th and 100ths foot scales. This was apparently a special order item, and today commands a greater collector value. Fine
