I make it a practice to avoid using metal cased transformers of any age. Most prewar trains will run fine with a postwar Lionel transformer such as an LW or ZW. If I wanted more voltage, I'd use a "Z".
I recently purchased a 1945 Lionel set from its original owner. The outfit came with both an "R" and a "Q" transformer. Both are in nice shape, with the original cord still pliable. I'll hold onto them, but I won't use them due to their metal cases.
