old Rivarossi engines and large flanges

I have seen this done by replacing the drivers on the Y6b with the next 
largest diameter Rivarossi drivers which I think were from the B&O 2-10-2. 
The replacement drivers had their flanges turned down.  Because the 
Rivarossi drivers were undersized in diameter (due to oversize flanges), the 
diameter of the replaced drivers looked right. This was done by Courtney 
Bennington of Winchester, VA.  He had the tooling and the skills to do it. 
Downside was that the Y6b sat too high above the rails, especially looking 
at the pilot.  This was in the 1970's when you could buy all the driver 
assemblies you needed for not much money.  I remember Gilbert's in 
Gettysburg having a large stock of Rivarossi AHM parts.
