Dan I think a number of us still have Letraset catalogues that date from that time… but mine’s currently buried in a packing crate! Last time I saw a Letraset catalogue for sale it was $2 - invaluable!
To hazard a guess I think these characters might come from the old Helvetica Condensed Black (not the NeueHelvetica) or possibly one of the Condensed Grotesques (Monotype? Stephenson Blake?) that Letraset had licensed. Looks like there’s a slight fattening in the strokes.

Ha! I’ll double your $2 to give you a little incentive for digging out the catalogue. ;)

Thank you for at least giving me a direction to begin my search. I really appreciate the help.

I’ve got an old Letraset catalog. Helvetica Compact seems to be the best match for the D and the colon. The V may be from Univers 67.

Ah, the joy of building new typographic forms from multiple sheets of used Letraset… those were the days, eh Mark?

Oh, I never did anything like that. I was always trying to make Letraset look like I’d sent out for type when we had no budget for sending out for type. That’s how I learned about spacing.

Oh yes, the old days.

Anybody remember rubylith?

Oh yeah. Rubylith and waxers and Letratone and Leroy mechanical lettering sets and line cameras and having to change the tungsten-carbide rods in the flip-top, arc lamp-powered plate burner.

Thanks again for the help!

Mark, I’ve found a letraset sheet set that contains Helvetica Compact, and pending better pics, it looks like it might match!

I haven’t been able to source a Univers sheet yet, but checking the font does show some promise!

Also, if the area in the picture is roughly one inch tall and 1/4th of an inch wide, what point size font would I be looking for? Sorry for the newbish questions; I’m a web-guy and get quite lost outside of pixels.

Besides Ebay, are there any other places to pick up one of those old Letraset catalogs? If anyone has an extra one, I’d be interested in buying it.

The trouble with old Letraset is that it dries out and is very difficult to apply you might be better served by scanning a rubbed down letter (as greyscale, so final size is about 1200 dpi) and manipulating them in Photoshop to get the size and position. I expect most Letraset catalogues got thrown out in the 80s with the rubylith and snopaque, so finding one could be tricky.
