I have your Spirit of 76 Train Set.  Unfortunately, my children have mishandled it over the years and am looking for some replacement parts.  I checked your parts catalog and could not find any parts for this model.  Also, there is no model number on the locomotive or box cars.

Here is what I am looking for:

1.  Retaining pin for the Locomotive drive assembly. Two needed, one required. 
2.  Coupling pin for the Locomotive and one for George Washington box car.
.  The main assembly is there, but the moveable latch is gone.  Two needed.
3.  Retaining pins for wheel assemblies on Box Cars.  Four needed.
4.  Box Car, Benjamin Franklin, wheel base assembly with wheels.  One needed.
5.  Left hand side rail assembly for Locomotive.  One required.

Can you help me.

Joe
