E4T beam deflection tube

This valve measures 70x20mm overall and has a B9A base

Data is needed about this valve, however see E80T which appears structurally identical. The only visible difference between the two is the presence of a getter deposit on the E4T but not the E80T. The E4T has the writing "4210EC.45." around the anode connector.
