Other than the nuisance of cross-Pond shipping I'd be interested as long as the bottom base is hollow so I can stick magnets in there.

Then again, if my old neighbor can make some base holders from scrap windowframes separating pieces for casing may become moot... If I were designing a case for you guys with U-channel sections to slot bases into, would brass U-channel in a wooden case be acceptable or do I need All Wood All The Time for period feel?
