Heathkit buying 5

Product Name: Heathkit buying 5
Heathkit O-8 scope. The design is based upon a 5CP1 CRT as used in various WWII Military radars and IFF sets; the tube was introduced by Tung Sol in 1944. The Scope kit was built in 1952, still has all original parts and manual ! Heath apparently bought a ton of surplus military electronic parts after WWII, including a bunch of 5CP1 tubes. I understand their first or second kit was a 5″ scope, the O-8 came sometime later. Still needs some additional cleaning – and then there's those waxed-paper buying capacitors that look suspicious.
