"I was told a while ago that this driver (1-7/8" across the wheel (not the flange)) was used on an early AF steam loco (4694 perhaps)."

This is correct. Never had one, but the Ives Casting used for the 4694 had the smaller wheels. No other steam had these wheels that I am aware of Jim. It was the same dimeter at the tread that the electrics used.

Thanks Rob - I guess I should have asked you first. I am a novice in the Ives 1134/AF steamer string. Like up, but can never get the AF stuff straight.

The Ives Casting used on the 4694 does use a smaller wheel.  I know that MEW did make this wheel at one time, but if they no longer have the tooling, then not sure what to tell you. 

At one time, I had two sets of these wheels, but used one on my 4694 and must have sold or traded the other set, as I cannot find it.
