welcome sir.
yeah milchcows are available. i cant think where off the top of my head tho. if i remember rightly they should be listed in the gwx manual. also, the next time youre in yer campaign, press F1 and they should be listed with relevant locations and dates.
will this be enough to get u all the way accross the atlantic and back...? i dont know, as im a novice myself and havent tried it yet. ive got a feeling youd be better off with a type IX
good luck
