I do not Joe. I thought they were made in Alamo, until I viewed the name plate on your bike. I was born in SF and lived in Daly City before my parents moved the family to the east bay in the early 1960's.
I don't recall the Pit Stop, but remember House of Scrambles, a Bultaco Ossa dealer, along with other oddities in Daly City. Also remember a commercial slot car raceway on Mission St. as well.
I recall the Trojan to be more of a utilitarian bike, when compared to Bonanza, Taco and others, but they were a capable mini. The neighbor kid had one where I lived and it was quite wheelie prone, (compared to my Bonanza) even with the 3 1/2 hp Tecumseh engine.
