Inquiry?? Carl Horner Cabinets
 

Anyone know of a good source of these aside from occasionally popping up at major auction houses?? Just now getting back to the hobby after several years being out of the loop :)

I doubt there is a good source for them. They are too scarce, And I would say that you could get lucky and find one on ebay or like you said, an auction house. Posting your wants on this forum can bear fruit too.
