The first version is the earlist which produced in 1952,No edges on mica,plate had one hole and one middle bar,black mercury,straight D getter.(the first one on the left)
Second version No edges on mica,plate had one hole and one middle bar,silver mercury,straight D getter.
third version Four edges on top mica,plate had one hole and one middle bar,straight D getter.
fourth version Four edges on top mica,plate had two holes and two bars,wing D getter.

Thanks shoot,so I miss the black mercury version.

As the First and the Second Version are construction identically apart from the color of the mercury,I will say these are the same Valves due to the different of the burning proceed of the getter result to a different color mercury.

I was confused before i got those tubes,why there's a additional getter supporter with no getter on it in telefunken ecc801s .after i got those early version ecc801s i came to understand that it's a evolution remains.just like human's caudal
