Entirely possible. Philco was notorious for using up unused parts, even to the extent of making up very limited run Phactory Phranken-Philcos, especially in the 1932-34 era. I have two of those, and both are grandfather clocks - one has a 52 chassis, the other has an 89 (!) chassis.

Oh, I saw the 49-900 on eBay you are referring to, but I thought it looked more dark brown than ebony even though the seller calls it ebony. In any event, I won't be competing against you if you decide to go for it.
