Just on the rather remote chance that someone has any information,
I'm the current owner of the Bursens/Arburo dance organ that was
once owned by Judge Roy Hofheintz and exhibited in the mid-1960s
at his Houston Astroworld amusement park, prior to its being taken
over by Six Flags in 1975.

If anyone has a picture of the organ while it was in Texas I'd very
much like to have a copy!

Cheers,
