Unfortunately, it appears that this conversion is wrong and inaccurate. While I haven’t looked at the crane closely, the mounting is completely wrong. The 9/2 did not have solid deck between the fenders. The 9/2 was built using a custom frame that was wider, longer and also deeper at the rear then the regular Famo. The turntable mounting for the crane was slung between the two frame members and the rest of the frame was completely open, so all the torsion bar mountings are exposed. There is no solid floor or deck mounted anywhere between the frame rails at the rear.
If you want an accurate model, I would suggest searching out the Panzer Concepts conversion that was released a few years ago (although now unavailable direct from Panzer Concepts). It has a completely new, accurate frame with all the necessary details.
