hi,
I have had that meter IIRC, since about 1970, never used it, still in its original box.!
In 1970 it was still Radiospares, I think it was mid/late 70's when they changed to RS.
Sadly a long time after my school days which ended in 1948.....
I left in 1971, I'm not 'quite' as experienced as you
As I posted the other day, the first RS catalog I saw, was A6 size, about a dozen pages. RF coils and solid dielectric tuning caps.
I did have some pre war Camm's comics, gave them to a guy who lectures on classical electronics.
I used to have loads of old magazines, I threw them all away a few years back now.
Perhaps you might like the following scan I just did, it shows how the logo used to be - and is an item I've still got 'in stock' at work.
I'm sure you will be able to convert the price on it!
