This may be a dumb question, but I was looking at roller tables in my bestfit book, and a 41R roller table has the same dimensions as a 148R (180/80/36 )
The 41R is used on a regular movement, and the 148R is used on an Incabloc movement.
But the difference between an Incabloc and regular I thought was only in the way the balance staff was pivoted.
So is there a difference in the roller, or is this just for added confusion.
Thanks to anyone who answers.
