Many thanks, Tim and Bill, for your replies.
Tim, you're absolutely right about the method for hand-cutting punches. I have tried hand-cutting a few crude isolated letters in brass in the past, but doing a whole matching alphabet of letters in steel all at exactly 3mm might be well beyond my skill level, now and forever. There's a fascinating description of a punchcutter ("Basil Walker, the last traditional touchmark maker in Sheffield" at work in Tom Conroy's book "Bookbinders' Finishing Tool Makers"
, (edit no. 4: what the heck is that smiley doing there? It's meant to be a close bracket) which sums up the talent required:
"In the next two hours I (Ashley Iles) was to learn that there is more to a three-cornered file than sharpening a saw. He (Basil) was just starting to make by hand a mark BEL AIR and apologised for having to use 3x magnifying spectacles for which he blamed his 57 years…The mark on the hand was to be 1/16" letters. Putting a piece of steel one and a quarter by half inch section and two inch long upright in his leg vise, he filed the top dead flat and marked a centre line both ways with a scriber and file. Next he reached for an old tobacco tin containing the master marks for 1/16" letters that he had made 30 years ago. With these he punched in the cavities of the letters: two holes for the B, one hole for the A and R, keeping in mind that the reading is in reverse. At each hammer blow he gave a grunt of satisfaction, knowing that each hole was the right depth and space dead in line for letters still to be created. Then with a rough file he chamfered the edges down to the exact size of the letters. Picking up a small three-cornered file, cursing the shortage and cost of them, he attacked the actual letters in earnest. These came to life as if by magic. Then he produced a brief striking block and tested the mark on a piece of white card. Basil pointed out that BEL AIR was plain lettering. It would be more difficult if the letters had serifs."
Bill (peak4), thanks for the link to Little Freckle. I've just realised that a place I buy stuff from already (Cookson) also sells these Impressart punches. I'm going to give Pryor Marking a ring tomorrow and if they can't fix me up with a serifed font at a modest price I may go for the "Newsprint Uppercase 3mm" premium sets of letters and numbers – not an ideal face but better than all other alternatives so far.
