All German…the black one, made by Compass (LOL) holds a 1.18 or a 1.0 mm lead in a spring clutch operated by the side button. The others are twist locks for 2 mm lead made by Tecnocomp (silver) and Tecnostyl (found the “L”)…pretty sure those two came from the same maker. In the black one, the pin slides out and on the others the pin rotates out of the compass leg…
I think it’s Tecnostyl (final “L”); Italian maker of some of the best drafting boards we’ve produced (but an expert I know maintains the very best were made by Neolt).
Tecnostyl is still around, but finding its drafting tables on the online shop is harder and harder, as the company has transitioned into one mostly working in visual communication. I remember their full range of solutions, it was majestic — ginormous light tables with integrated orthogonal drafting arms, fully customisable — and they even rebranded some leadholders from the 5611 and 5616 KIN lineup…
I’ll join the club with this successful trade with @DarkwingDuck . The PSD5 is the star of this show, but I’m most impressed with Microlette. It gives me heavy PG5 vibes.
oh - it’s coming soon.. TBH I never thought I’d get my hands on one so never took serious notes on it. I need to do some homework, but it’s definitely on the list and near the top. (I have some requests from subscribers in queue, plus a few others I am half way finished with).
The original SV Sharp Silver. I know a collector who has a box of these.
The prototype R10 Silver Excalibur Rolling Writer. This is shown on the back of the 1973 Excalibur brochure. A prototype P1005 is in the collection above.
And the inferred SG5. I have never seen or heard of one, but all other Crown Excalibur pencils had a Japanese and Worldwide version. It also explains why they jumped to SG15 for the non-Excalibur pencil.
