What is this metal disc attached to front wheel?
Excuse my ignorance but can anyone tell me what this metal disc was used for thAt is attached to the front wheel of my 1940s sunbeam? I assume it may have to with a light setup such as a dyno hub? Thanks!

Ha! I've seen those connected to bar-mounted odometers... it turns a litte white cog (that seems to be missing from yours)....

Well i tracked it down thanks to your help. It appears to be a part from a vintage Stewart Warner Speedometer

Good guess, but I recognize that as a frambulator. Very rare, that's only the third one I've ever seen.

No, no. On those old English bikes you want decent frambulation, or the magneto reluctance and capacitive directance will get the better of the rider. And you definitely don't want that.

Now I am confused. I thought the flux capacitor was maximized with the reverberations of each rim rotation through the orbital sphere? Or is that just for Italian bikes?

Apparently. Bicycles are from Europe. Pizzas are from Italy.

Don't laugh, folks. I score/time 5K/10K/triathlons, up to marathons. Current course certification, in NC, anyway, is with a Jones counter, and it uses a piece just like that. You get a laser-measured 1000 meter course, ride it twice to calibrate the counter, then use the counter to measure your courses by bike. They have yet to accept GPS measuring, even with .00 units. I bought a Cateye with .00 units, as well, and while I thought it worked fine, and was accurate, and was willing to calibrate it on the 1000-meter course, it was not acceptable. The funny thing is, you have to add .1 of 1% anyway, so a perfectly accurate 10K course will still be 160' longer than 10K.
Experienced runners can tell if a course is long or short, anyway. You run enough 10K's and 5K's, you know if the course is long or short (if it's relatively flat).

The important thing to remember is with respect to English bikes. As you well know, capacitors are polarized, so English machines are positive earth. That's a mistake one will only make once.

Positive earth it is! (or is it?)

Due to the hypocritical relaxation of certain moral and ethical standards, civilization has gradually descended into those base depths of vulgar degradation, amply exemplified by internal reactionary culmination. However . . .
