[Milsurplus] Identify some small modules?

[Ian Wilson]

Thanks all,

The best bet so far (guessing at the actual sizes of things from
photographs always being a risky business) is that these are modules
from R-394/U. This appears to have been used in lots of equipment, such
as the VRC-19.

If anyone has schematics that would be interesting; not a high priority
item, since I can't think of a hot project that will use these modules.

There is an interesting subassembly in the "2nd IF Discriminator". It's
a 5" long metal box, with a pair of connections at each end. I would
guess that this is a delay line - is that the technology used for WBFM
discriminators in this equipment?
