I suspect you would have to unscrew the knurled caps and have a look inside to be sure .. the possibilities that come to mind:
Ferrites as part of the duplexer arrangement?
Gas discharge tubes ... a "thing" in radar is small gas discharge tubes that ignite and conduct during each transmission pulse, the conducting gas acts as a high speed switch, shorting out the waveguide and preventing too much of the TX pulse getting into the crystal detector. Normally I would expect them to be across the centre of the tube though, and these appear to be at the edge.
RF Sampling ports?
Was the WG pressurised with nitrogen ?
