The HP sig. gen.: middle shelf, LHS: behind the hood of the Anglepoise lamp. It's a 8640B. And, IMHO, it's a far better sig. gen. than anything that Marconi ever made. Just a shame about the material that was used for the gears within it: they tend to disintegrate. But that is a problem that is usually fixable.
And talking of Marconi, yes, that is a TF1041: substantially modified out of necessity, of course! Behind it is a TF893 A.F. power output meter. "Behind it": yes, I really need a bigger workshop-cum-radio shack! It's just so easy to introduce yet another item into that domain than it is to turf something out. The "Wait a minute: that might just come in useful one day!" is an attitude that is very hard to suppress. Only recently I was making something and used a small item that I have been carrying around with me for over 50 years!
