German Unit: 75 IG - Limbered Movement?

[rules_heretic]

I was collecting up the German 75 IG I have from various games, and I noticed that the Limbered Movement is listed inconsistently.

I looked at the units here in the Library but don't see (and could have missed!) where the Limbered side information is shown.

Some of the counters show 1MP when Limbered.  Others just show T for Tow required.


Based on what it is, I think the 1MP version is probably best but am interested in what the correct answer really is supposed to be.


Side Note Question:  What's the Limbered Movement of the 75RCL?  (Again I am not sure that this information is available in the Unit Library.)
