Your observation about most pen collectors is something I totally agree with - it's like they completely miss the point of why these pens are important, namely how they write and how they were designed, not just that they're rare or weird. That said, not caring about the details of what makes a great pen great just seems to be missing an important part of the story of the pen and why it's important. It's just like the liner notes on a record album. If the music sucks you don't care who played the drums. If the music is incredibly good you want to know and you seek that information to know more of the inspired story behind what made it happen.
I believe that the Greek key pattern on the cap band is the Greek Border pattern because that's what Wahl called that pattern on their All Metal Pens and their chased hard rubber pens in the 1920s.
Supposedly Wahl's Tempoint pens were based on designs they had acquired from the Tempoint Pen Company at about the same time they acquired most of the Boston Pen Company in 1918. The few Tempoint nibs I have don't seem to be less flexible or less interesting than Wahl's later Wahl imprinted nibs, but I'm looking forward to seeing seeing what you discover in the course of this video.
The downward beak bend was often used during the period to add rigidity and reduce the flex slightly, you can find this tip shape on a metric ass ton of waterman safety pens
Also the older the pen, being true iridium, it tends to be more porous as opposed to later styles adopted that were less porous and capable of wetting the nib tip with a better quality “iridium”
Iirc, the bought the Boston pen company for the designs and body manufacturing capabilities and they bought tempoint so they could have in house nib production capability.
I think that Wahl with the roller clip jammed into the cap to replace the original clip was a part of one of my junk lots that I sold recently. It was nibless, so the seller must have put that tempoint nib on it He also complained about the lot and made me refund him 50 dollars. Unlike him, I mentioned the f-- up clip.
