I have the 3 part numbers of the coils - 10M (870138). 15M (870135) and 20M
coil (870369). There is also a 40M coil on top of the flat washer with no
part number on it. The flat washer has holes which appear to have been a
groundplane or a cap. hat.

Seems to be an HyGain 18AVT. The coil on top is the 80M resonator. The flat washer is for the 4 top radials (11 1/4" long).
