That's really cool 8)
I've got a late 40's Waterman 'Pocket Scope' - similar design but larger 3" crt. Replaced the dried up 2-prong line cord + a few old paper caps and it still works fine. I use it for audio signal decoration and some ucontroller vector projects.
Don't have access to photos of my scope, but here is a link to the same model I have (with scan of operating manual)

Seems Dazz has made new friends but none of them seem to have the porcelain valve holder I might have. :P

I'm guessing you didn't read post #71 on the radio forum?

He is sending me valve bases and a can all the way from the UK at no charge. Very generous and helpful. No chance of me buying valve bases locally.

Hi
Some more photos.
A selenium diode in pieces. Just disks held together with springs.
Some leaking caps.
Soaking a seized potentiometer in hot kerosene in an egg cup, in a bowl of boiling water. It worked really well.
A close up reference photo before I cut out and replace mica caps, encased in bakelite, covered in wax.
