Not a bad kit; the Sd.Kfz. 7/1. The chassis has some minor issues with wheel spacing, though.
Trumpeter would have you add the gear shift levers, etc. to the top of the gear box. While accurate, they will just get broken off during construction so add them later before you fit the armored cab.
I think the wheel spacing issue is due to the frame being too long and as for the gear levers, I too had to leave them off as there is no way you can put the cab floor on with them attached (I built the 7 Late). Also Trumpeter flubbed up the front fenders on the original release and have never fixed them on any subsequent release although the problem is well documented. Your off to a good start.
