Its a tough little radio, not only used for long range communications but also did double duty as the ships DF receiver. entirely all aluminum. also used a "magic eye" tube for "tune to max" being that required less circuitry. The reduction tuning was a bunch of slip clutches or something like that with no big machined gears like US sets . Once taken all apart and cleaned was a surprising good action and works well on the Ham bands. Somehow thew receiver works great being sensitive, selective  and with a more usable band spread for the Ham bands then its US counterpart the BC-348, its also smaller and lighter then a BC-348. 
I would think the biggest challenge for anyone serious about that receiver is first finding one with all the DF circuit still intact being that's the first thing everyone allays pulled out and then the crazy Brit capacitor cans. from what i recall they were a can maybe three inches long and five eights wide that housed all the bypass capacitors for one or two stages. the capacitors would all open but if that was not bad enough the can had four red wires , one for each section and a black wire that were manufactured from some form of plastic that on the two i have seen deteriorate to the extend that touching them the insulation falls off.
Another interesting problem is that the radio is not SAE or Metric, so all the hardware is unique to that radio, so simple things like screws or nuts are a real issue.
Speculation : this receiver was as common in Europe as the BC-348 was here. I hate to say it but the BC-348 is build like a battleship in comparison to the R-1155 but the R-1155 was smaller, must have cost less to build and included a direction finder, what was the better receiver?

I had never seen the inside of an R-1155 before. My, they really conserved metal, didn't they?
Yes, i do understand British industry was being pummeled at this time, while U.S. industry was safe behind the oceans, with vast resources at its disposal.
