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).

Same questions asked on QRZ.COM last week. Couple of OMs had the manual --
search there.
