Having taken a recent interest in Eddystone receivers, I found out the 
screws used in many British rigs are BA, British Association. They are 
metric, but the thread pitch and shape is different from the ISO metric 
we usually see today. Replacements are available from places catering to 
restoring British motorbikes. One source in the USA is at  
"britishfasteners.com"   I have an intact R-1155, and want to find a 
T-1154 to go with it before I dig into restoring it. A fellow in England 
has a nice pair, but wants 1000 pounds for the pair, and the shipping 
would be  250 more. A pound is about $1.25. The dynamotors or "rotary 
transformers" for the rigs are exceptionally difficult to find, as is 
the AC power supply. However, the AC supply will work on 120 volts.  The 
transmitter is less powerful than the BC-375, especially on AM where it 
is grid modulated.  I think the BC-348 has an edge in performance over 
the R-1155.  I have not heard anything negative about the reliability if 
the R-1155/T-1154, they are definately built with material conservation 
in mind but seemed to stand up in combat well enough. I have downloaded 
considerable information and manuals on these rigs and can share if you 
can receive large emails.
