Hi Al,
 
Yes there is.  Some carriages have been enlarged slightly by owners cleaning 
rust or whatever.  On my large carriages I intentionally enlarged them a bit so 
diamond B's that are slightly swelled will fit, I find it better to do this 
than to remove the nickel plating from the pot metal reproducers.  Of my four 
large carriages one was enlarged and three were original size.  I enlarged two 
of them and kept one original that way slightly swelled reproducers will fit.  
The difference is not visible to the eye, but it can be enough for some 
reproducers to fit.   
 
Does your O have the nickel plating on the part that fits into the carriage?  
If so and it almost fits I recommend enlarging the carriage.  If it has already 
been worked on you can have it machined, John Nagy does excellent work.  On my 
carriages I used a Dremel tool to enlarge them.
