Mystery collector, with initials "CGK"?

[PeterF]

Hi -

I recently acquired a nice machine from an estate sale picker, and upon close inspection just discovered a subtly-placed dymo label on it with the initials "C. G. K."

Does anyone know of, or remember a possibly-deceased, collector with those initials, possibly located in northern California or southern Oregon?

Machine is a bit special and was with other phonos at the sale, so it is definitely not from the estate of a non-collector.

I'm just kind of curious. This same sort of question once led to me finding out that I had purchased a couple of machines that had once belonged to Art Wilmoth.

Thanks.
