OK, maybe just a little.
This week I received by way of the nice man from the gub'ment a nearly bright and shiney, new (to me) Lufkin 6" combination square. It is a little stiff and will require disassembly and cleaning. Mostly a small amount of rubbing out the faces of the rule with some 600X (followed up with a hard block) and WD-40 (1). In all I figure 15 to 20 minutes.
I paid $18.03 for it. Comparable new (Starrett) would cost you $50-$60. Where did I find this sweet little gem at such low, low prices? eBay. All you have to do is throw down $20 on every combination square that comes up. Sooner or later you'll snag something and it'll follow you home.
My new Starrett 6" combo is being retired to the drawer for the next decade or two to allow it to vintage.
(1) Never use Scotch Bright or steel wool on the face of a rule. The trouble is they tend to dip down into the engraving and remove the crispness. Also, they take out the paint in the engraving and make the rule hard to read.
