I wonder if by some chance the hole spacing will match my Cat 212 on the one you want to sell.
My 212 sits right behinf the D in the shed. it would not take long to find out.
There is a guy located on the No. Calif. coast (Eureka I think) that makes cutting edges to order.
A couple of my friends have used and recommend him.
I can find out more if you're interested.
