I moved the Sonderwagen 4 from Thyssen to Thyssen Henschel as apparently it was rather that name: https://en.wikipedia.org/wiki/TM-170

Then remain the older ones (2 & 3) :

These would rather be from MOWAG according to https://en.wikipedia.org/wiki/Mowag_MR_8
Is there a reason why these were listed as Thyssen?
