Very nice Lufkin 35 - 12" Graduated 2506R Tempered Steel Blade and Hardened Try Square with Level and Scribe.

The 2506R is graduated in 50ths of an inch. If you were working with from a blueprint with decimal dimensions, (Instead of fractions) this would be the right blade to use. All four edges have the same graduated .100 increments numbered with 50th of an inch fine graduations.

In excellent condition.

The try square has a nice large scribe, (Bigger than most.)

It is hardened and has clean sharp edges. There is a small "pitted" spot on one edge that can be seen in the photos.

Slides and locks well.
