Thanks for posting.
Had one or two of these pass through me workshop in California.
Suspect there must have been a distributor for them in the state as observed a few others "in the field" locally.
For some reason nearly every example seen was yellow.
(Sutter an actual manufacturer)
The company had a pro bike done for them by Olmo in the early 1970's - shown at CR.
