what about a 41-285

You might have a harder time finding a 41-285 cabinet but who knows, however there were lots of 41-280 and 42-380X consoles sold so if you are in the North East it should be fairly easy finding an empty cabinet. The 38-4XX and 38-7XX style cabinets should also be easy to find, I know of a guy in Chicago that may have one right now. What I would do is go on the Antique Radio Forums as well and ask for an empty cabinet similar to what you want, in the North East there should be be at least one nearby.

P.S If the lady is chucking out a 38-2XX I would take it anyhow, someone would likely trade you an empty cabinet for it and possibly give you a little cast if most of it is there.
