HO/OO RWS Awdry Kipper Van Chassis Chain

This product is the intended chassis for my HO/OO RWS Awdry Kipper Van shell products.  Links to those shells will be included below.  The Bachmann version of this product features the International Hook & Loop coupling system, with hooks included.  The Chain version does not feature the international Hook & Loop coupling system, instead being intended for the more realistic 3-chain and hook coupling system.  In order for the bogies to attach to the chassis of this 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.  Beyond the screws and nuts, you will also need to provide two sets of two HO scale 33" wheels for each bogie in order for the model to run.
