Glen VLeon,
You left Boston Store off your list.
There are the E121 backs - Holsum Bread, Gassler's, Standard Biscuit, Johnson Candy, etc. (which you probably already have - you can complete the list for me)
The T205, T206, & T207 backs should have some challenges. Do you have the D304 backs - Brunners, General Baking, Weber, Martzen(sp?) Also did anyone determine if the E222's had different backs?
