My 60+ year old Deardorff 5x7 has served me well for most of its life. I also have a 4x5 back for it which actually makes it essentially the Deardorff 4x5 Special. I even have the unusual, I hesitate to say rare, 2 1/4 X 3 1/4 back for it.

By the way, the original bellows is stilll in excellent condition.
