Re: Odd 453A on ebay UK

I'm 99% sure it's a 453 tube in there, and it was probably like that when his Dad bought it back in 89.
It in part might explain his defensive responses (that's the polite way of describing his replies).
But, he's also 100% sure that the graticle is no part of the CRT:
"The tube is just a Tube , it has NO screen markings , the markings you are looking at are on the fitted escutcheon plate . No Tube on any ‘scope ever made has markings on it ."
Flat earth.

Perhaps if a few more "anoraks" message him he might at some point see light?
