With the recent discussion on Companion Sliding T-Bevel Squares I was able
to get Karen to check mine out. I have the Sears Model 39582.
It is probably a little smaller than some others but I really like mine. To
release the blade there is a large knurl type nut that does not get in the
way. At the end where the blade is controlled the handle is cut down so that
the nut will not protrude and either side can lay flat. The only thing
written on the blade is Sears, model number and made in USA.I assume that
they still sell them mine was my dad's I would guess it to be about 25 years
old.
