Dear Fellows,

I have these 4 complete Eisemann mags from which I want to make 2.
They are in pretty good shape.

However, I am confused about the rotors.

Mags #1 and #2 were assembled on one engine
#1 with impulse coupling and #2 without.
Mags #3 and #4 on another.
#4 with and #3 without.

The ruler is sitting on the bearing's seat. So the red arrows are a measure of the length of each rotor.
#2 and #4 seems to have the same length. #1 seems to be a little bit shorter.
#3 is definitely the shortest.

With impulse: #1 and #4.
Without impulse: #2 and #3

So I wonder what is the correct combination of rotor length and impulse/no impulse...
The Eisemann manual does not help.
The rotors have no part number stamped on them.
Could anyone be of help?

Thanks
Tom
