How to tell if TUnze is 6000 or 6100 model?

I recently purchased two tunze 6000 from a person on reef central but when I got them I noticed on the back of the pump they had 6100.10 on them does that mean they are Tunze 6100 Streams or could they be Tunze 6000 streams.

It is just the part number of the motor which they both share. On a 6000, the transformer will say 7210.202.

Yeh, I got suckered into buying what I thought were 6100's used from a member here. I later found out, after ordering 6000 transformers to use on my smaller tank, they were indeed 6000's Still saved me some money initially, but now I have an extra set of 6000 transformers.
