[Lowfer] Gang Capacitor ID?

[Mike Staines - WM1KE]

If I am not mistaken, that appears to be the tuning section to an (old)
National Radio HRO-series Regenerative receiver. The kind with the
changeable plug-in coils. Plug-in coils, were actually quite large and
slid, rack-style, into the front of the unit.

The tuning cap can be seen here:

Although I think that this particular cap is from a more recent model,
perhaps a 60's era HRO-500.
