[time-nuts] CRT for Tracor 527A

[David C. Partridge]

Trying a long shot here, I'm looking for a 1" CRT type 1EP1 (or 1EP11, or?)
for a Tracor 527A Frequency Difference Meter.
 
I did spot some on eBay but the vendor had a rather high opinion of their
worth :) at over 300 dollars

Anyone got one to spare?

Thanks
Dave
