Ferret and SDKFZ clone

[shrapnel]

A friend of mine and myself just recently acquired two new toys: a Ferret and and what seems to be a Tatra OT 180 transformed as an SDKFZ 251... Now, I just ordered a set of manuals from England for the Ferret but I can't find anything on the SDKFZ/OT 180! Since these two have been sitting in a barn for about 3 years, they do not just strat up and run... And even if they could, we have no idea how to operate them, let alone service them... Anyone has any documentation on the Ot 180 or the german SDKFZ?? At least the starting routine and where the diesel goes would help! :-)
