Old Rotor cranks that did funny things with timing?

Doubt it, after looking further at it.
MMC (Magic Motorcycle Components) crank?
Bullseye cranks?
Not MMC. Cyclone? Arm shape is about right, but the spider is a little different than the version I’ve seen.
white industry crank and b.b. .
Ahh, the Campy Frame Extender, circa 1982. Am I right?!?
That is a good mystery pic. I was thinking Prototype Action-Tec crankset and BB? Or a Gonzo Ti Bb and crank?
Look like Bullseye cranks to me.
Campy Seatpost.
Dan/Ed cranks. Ahead of their time. I think they even had a belt drive too
daggone it! I saw these once when I was looking at a new crank system for Icon. The spindle shape was perfect and replicated beam loading from a textbook point of view. I can’t stress my brain enough to find the right cells with the answer. Beer probably washed them away, anyway. I’m thinking McMahon or something like that. When do we get the answer?
fo sho DanEd with a big ol’ U.S.A. machined on the outside. and a nice bb conversion and hexagonal spindle to arm interface.
What is with the bb? How does it attach to a frame? 2
1950s campy track seatpost, to be exacter.
Belt drive version @ http://www.mombat.org/MOMBAT/Bikes/1995_DanEd_Red.html
Is there a chance that it could be a Mrazek …. I recall that they also made a machined SS and alu crank … but I would have to surf through my mid 90′s editions of MTB Action to be sure.
@kurti_sc: And the pockets in the crank arms precisely coincide with the highest stressed area XD
prototype raceface crankset
Answer from Jeff at First Flight Bicycles: “Dan/Ed or Dan-Ed Crank, first names of the guys who owned the company.” Also, see his link (jeff’s comment above) for the belt-drive version.
It’s a potatooooo!
