I have two receivers from the 1940s which might test the memories of
even the real experts.

Wilcox F3 Receiver, five tubes plus rectifier, crystal controlled
fixed tuned AM receiver, rack mount. With the orginal hard bound
manual. The label on the front says it is set for 5.000 Mcs. This one
appears complete and unmolested inside. I am sure that the paper and
electrolytic caps need replacement, otherwise looks very good.

Wilcox CW3 Receiver, five tube design plus rectifier, crystal
controlled fixed tuned CW receiver. rack mount. With the orginal hard
bound manual. This one lacks some covers, antenna coil, and crystal,
and has loose wires inside. Probably restorable, but that will require
some effort. The circuit is classic single conversion superhetrodyne.
The layout is clean and has convenient access.

Is anyone interested in either or both? Zip code is 19350. I could
take pictures if asked.

Not likely. The June 1968 issue of "73" was completely about surplus,
and right there on page 28 is an article by Hank Olson about the Wilcox
F3 (and he has an aside about the CW3 which seems to indicate they
may be quite similar. He even mentions there is a schematic for
the F3 in the CQ "Surplus Schematics Handbook".

I had a similar crystal controlled receiver back in 1972 or so, though
it was lacking markings so I never knew what it was.

If you can get hold of a copy of the "Surplus Schematics Handbook"
edited by Kenneth B Grayson, W2HDM which was published by the Cowan
Publishing Corp.(CQ Magazine Technical Series).

There were 4 models covering 1900Kc/s to 3600Kc/s

3100Kc/s to 6100Kc/s

5100Kc/s to 10000Kc/s

8100Kc/s to 16500Kc/s

This was before we had Mhz, Hi

There is a circuit and parts list in the F3 receiver in the above
publication.
