Anyone heard of them?

They apparently vanished in 1929. I don't know if they made a
complete airplane or just hardware. (Interesting turn-buckle:
threaded 12-28.)

Any information would be warmly apprecaited.

Nothing on them in Aero-Files, which is incredibly comprehensive.

Perhaps someone at the Western Aerospace Museum knows something.
Oakland was a hotbed of aviation activity in that time frame.

I got foncused for a minute, as there used to be a plant on High
Street off of San Leandro Blvd that built RUUD water heaters, and I
wondered if this aviation enterprise might have been a spin off, but
this was a deluded edifice of my own creation.
