[Boatanchors] Info for Johnson 167-302 differential capacitor

[Michael D. Harmon]

Does anyone have info on an EF Johnson 167-302 variable capacitor?

Better yet, does anyone have a scan of an old Johnson catalog which 
includes this capacitor?

I'm working on an old receiver, and I'd like to see what the specs are.

Thanks!
