They might be a pair of R216 Receivers and PSU’s, but I have no idea if that would be part of the Larkspur series or Clansman, or even what frequencies they lurked about on.

 Spot on David. They are a pair of R216 receivers with PSU #45. These are a vhf monitor/intercept receiver covering 19 MHz to 157 MHz. They are a part of the Larkspur family.
