I have 8,000 fonts available.
I don't think that the Pfeil logo is a font. I think it is a graphic drawing - hand generated.
There are thousands of fonts now because it is easy to create them for computers. There are new ones every week. (variations on a theme)
In the good old days, when printing was done using type set zinc figures, hand set by type setters, the number of available fonts was quite limited.
Much more common for special badges and headings to be hand generated.
If it is a font, it will be very old and if not particularly common / popular it may never have been converted for use on computers.
Can you scan the badge or get a really good photo of it at high resolution. Photo taken from a couple of meters away - to avoid distortion of the image. From that I could make a good computer line drawing.
I knocked-up a now obsolete blue & yellow sticker from the 1960's for my scooter friend. He had a photo of the old one on the side of his glove box.
