WTB Looking to buy a Virpil Mongoose MT-50 or CM grip (but not the current CM2 model)

[AstroNomad]

I am interested in the older models of the Mongoose T-50 grips, either OG, MT-50 or CM (or some other I do not know about yet). 

But not the current model CM2. This is for a modding project so I hope to save a bit with an older model. Minor electronic problems are okay, as long as the plastic shell is fine. If you are not using yours, this could be good for both of us. I am based in Germany/EU.
