From left to right, you can see a T1154 and R1155, as used in Lancaster bombers, and totally obsolete by that time.
In the middle there are two bits of then-current equipment, below the R107 receiver and on top a TX whose number I've forgotten. (If someone recognises it, do please send me the information.)
The hand belongs to George, now G3PLY, who has exposed the innards of a WS19. This is actually the 19HP with a fairly linear amplifier which I think used four 807s in parallel. It was a very effective TVI generator (as was the T1154) but fortunately there weren't so many TVs around at that time.
