FX-1 S this an Fx 1 shaft or a superjet shaft?

[Bern]

I pulled this out of my 144 conversion and I can't remember if this is a short shaft from an fx1 or a superjet. This pic is bad from the back side of the coupler to the rear of the shaft is about 150 cm. I I put the tape on the front of the coupler it measures 160. Does this mean it is a superjet shaft ?

It has been a while since I looked at these and I appreciate any help.

I am looking to sell thus short shaft as well as an fx1 drive shaft.

fx-1 is 143mm tip to tip or 108mm from the tip to the shoulder where the coupler washer seats
