WANTED: Lid for Oxford (Columbia) BK or BKT

[Fonotone]

I'm looking for a lid for an Oxford BKT or BK. The lid should be approximately 12" by 7 ¼" deep. It's similar to the Columbia-branded equivalent but not identical. The Columbia lid has lower molding that's rounded at the corners. The bottom of the Oxford lid is square at the corners. Otherwise (I think) they're pretty much the same.
Thanks,
Grant

Actually, there are differences. The BKT/Oxford uses the same mechanism, but the pin striping is different. The BKT/Oxford case looks just like a BVT, but bigger to house the larger mechanism and motor. They were straight 2 min., and the later ones had a 2/4 min. set up.
