I wonder if it came from where I used to work ? In Mill Valley ? Looks exactly the same, even the name tag wear and, as you said, pretty rare model. Same geographical area, so could be ?
Kind of a sad story - that company, back half made sonar transducers for ships, front half was race car gears, owner had an Indy habit so there were five indy cars spread around and one whole building full of offlehowser engines, plus a couple of sports-racers. Dropped by last time I was nearby, now they sell cool skateboarder clothes imported from bangladesh. Flourescent, man.
