HO/OO Old Coach Generic Coach Seats Bachmann

This product is intended for effectively any of my Old Coach Shells.  The ideal match for each chassis should be evident by the titles.  (i.e. Old Coach Standard Coach Seats functions for both the 1st class and 3rd class shell while the Old Coach Brake Coach seats functions for the Brake Coach shell).  The "Generic" versions do not contain seats and could therefore be the chassis for any of the shells.  The difference between the Bachmann and Chain versions of the products is that the Bachmann versions feature the international Hook and Loop couplings, with hooks included, while the Chain versions do not.  The Chain versions are intended for the more realistic 3 chain and hook system.  Links to the Coach shells are included below.
