So far I'm glad you have stumbled onto an unusual 107. Still, your car holds more secrets. The info I got on your car is genuine and tells of where it was pointed to, but does not tell it's first human encounter!
A hydraulic unit installed for low temperature climate may be considered extrememly unusual, and rare for any automobile, especialy for a MB 107. Where was this car's first destination? North pole, south pole, Siberia, where????
It would be interesting to find out!
