HO/OO CCT Parcel Van Underframe Bogie Bachmann v1

This is the underframe for my CCT Parcel Van shell products.  The differences between v1 and v2 of the chassis is that v1 does not have foot ladders attached to the chassis while v2 does.  The difference between the 2-axle and the bogie version is that the 2-axle version only requires 2 sets of wheels, while the bogie version requires 4 sets of wheels (2 sets per each bogie).  In order for the bogies on the "bogie" versions to attach to the chassis of their model, you will need to buy a size #4 screw with the associated Hex nut.  The hex nut will fit in the hex shaped hole on the underside of the chassis and will require glue to stay in place.  The screw will then go through the hole in the bogie and screw into the hex nut attached to the chassis.  This particular iteration of the product features the international Hook and Loop coupling system, with the hooks included.  All this model needs in order to be ready to roll is a set of either Hornby 14.1mm or HO scale 38" wheels.
