Thank you for posting this! I've been looking off and on for this for ages and ages.

Trivial factoid: my understanding is that the Gorton pantograph fonts came first, and that the Leroy lettering sets were manufactured using the Gorton fonts. But I don't have a good source for that, so I could be completely wrong.

I had not heard of those brands, I had Rotring [1] lettering stencils to match some of their pens.
