It's a gizmo or thigamajig for scribing equidistant lines. Insert the scale in the flats, and the pencils or scribers in the uprights.

But....knowing Mass....It probably isn't.....back to the Lee Valley catalogue....lol

For some reason, I get the impression these are to be attached to a framing square. I've something vaguely similar for the repeated laying out of step stringers.

Although I've never previously seen these, I'm with loko... only would add "whatchamacallits" to his already identified names

Nicely done folks! If one takes keywords from all of the replies a complete picture is formed :^)

Tri-Scribe

These cunning left- and right-hand scribes convert any rule or combination square (with blades less than 3/32" thick and 2" wide) into a versatile marking tool. Attach one (or more) to a combination square to produce an efficient panel gauge, or fasten both to a ruler to create a trammel for circular work.

The scribes are zinc alloy with a powder-coat finish; the thumbscrews are blackened brass. High-carbon steel scratch-marking pins are included, but standard pencils (not included) can also be used.
