Not all punchcutter's tools will need their own discussion thread, so it might be useful to have a thread devoted to miscellaneous tools. Please add more!
I've added several more tools to the page at: http://circuitousroot.com/artifice/letters/press/typemaking/making-matrices/tools-of-the-hand-punchcutter-in-steel/gallery/index.html
Here are some representative images:
A "Lampe Olympe" and "Lampe Pigeon" as used at the I.N. and by Stan Nelson for soot transfers and smoke proofs. (But please note: Even though these lamps were designed for use with gasoline/petrol, NEVER use that fuel in them. I discuss the reasons for this on the page linked above, but basically the reason I'm adamant about this particular safety issue is that years ago a neighbor of mine was crippled by the consequences of using gasoline in his workshop. Gasoline/petrol is too dangerous ever to be allowed into the workshop. There are safer fuels.)
A fixed height-to-paper (type height) gauge.
A fixed type height gauge with a sliding square, after a design by Henry Barth, digitally reconstructed.
A face squareness gauge, by Stan Nelson.
A caliper-style type height and face squareness gauge.
