The cabinet and original trays appear to also be made of mahogany. There was absolutely no detectable aroma of cigars even on the actual surface of the original cigar trays.
The cabinet is probably from the early 20th century if not even from the late 19th, so yes there is
plenty of airflow within the cabinet, as over the years some of the joints have expanded and the lid does not close with any level of "air tightness". It certainly allows for better airflow than a 2x2 plastic
flip would.
Each of the trays is 5/8" thick (the close-up pics are deceiving). He requested them a
bit thicker and with deeper recess depths to hold specific
types of
Byzantine coins. It also required this configuration so as not to have to remove the original rails. We both felt it important to keep them so as to retain the "original-ness" of the antique. The original cigar trays
still fit on their original rails, and if desired the added rails could be removed without too much effort to restore it fully to its original state.
I too look forward to seeing a few pics with coins in place.
