RE: Ei KT90 Question

It is definitely not type 1 or 2.
Looks like type 3 due to "wing" structure where the two anode halves join.
Look for a silver metal square or circle on one side (without the square holes) of the anode plates. If it is square, it is type 3 prewar. If it is circular, it is type 4 post war.
