Info Required Coventry Climax Genset

[Bob Moseley (RIP)]

An acquaintance of mine has an operating generator powered by a Coventry Climax 4 cylinder air-cooled engine. He uses this as an auxilliary power supply in the event of bushfires. Unfortunately he doesn't possess any manuals for either the engine or generator. Anyone out there who can help?

The data plate for the engine has the following - SR/240/3026.

Data for the generator:

The generator is a GEC single phase made in England. 6kva 0.85 PF 50 cycles.
230v 26.1amps.
300 rpm - Cat No. XC/GEC/1386
SR SM 41328
187 TPL

Another plate lists:
Cat No. X2/XB 18150
Generating Sets AC
240v single phase
50 cycles

No. 1MK 1/??
WD B/32/cc/34
Unit No. SR 240/1/1419

I wouldn't have a clue what most of that means but there has to be an expert out there somewhere.
