Can anyone identify this GEC set? The case looks like the battery model BC3746 but it's an AC mains chassis.

Valve line-up is: Frequency changer -illegible, looks like FC4; IF - illegible, looks like VP4; Detector - illegible, looks like D42; Output - PenA4; Rectifier - IW4/350. I presume the last two are replacements as the originals would have been Marconi/Osram types - or am I wrong there?

Looks like the BC3740.

As you say, probably all Marconi-Osram valves to begin with.
