Bruce, Martin did a mini kit for the Fe-22 and Fe-23 cars which has ONE new end and new side sills, sells for $10.00, and is intended to be used with a Proto 2000 50 foot auto car with end door.
However you can make an Fe-21 using two of these mini kits (you need two new ends) and a proto 2000 50 foot single door car, which I have done. Martin has not made a mini kit for the
Fe-21 but the other parts can be used.
Martin will be in Southern california this coming weekend and he will have some of the mini kits
with him. He will be in Parris, California on Saturday March 4th, and Buena Park Holiday Inn on March 5th. He will also be at Winterail in Stockton, California on March 11th.
Sunshine will also release their newest Santa Fe kit next weekend at these events. That will be
a 50 foot box car kit that will make the Santa Fe Fe-6,7,8,9,10,11,13,14,16,18,and 20 class cars.
