Anyone know who made these Daylight diaphragms?

They look exactly like the diaphragms that came with the Golden Gate Depot SP Daylight passenger set I had. Those diaphragms were use between the three section articulated diner plus the articulated chair cars.

Thanks very much!

I’ll add, FWIW, that these are the older 3rd Rail diaphragms from the first run Daylights that had adhesive strips to hold them on. The most recent sets issued this year have magnets. Neither is a really perfect solution for these otherwise very fine cars, but they allow running them with diaphragms on 3rail O diameter tracks like O-72.
