Well, darn. I pulled the front wheels off for the first time and was surprised to find no maker name anywhere on them. They're standard Cobra 6-pins, provided by ERA with the original roller. Other than manufacturing marks (and numbers on each spoke/pin hole set) the only marks are
COBRA II and what looks like an elongated peace sign.
Trigos? PS? Halibrand (the spinners are Halibrand)? Kragar?
