hercus mill dividing head plates

I am an owner of a hercus mill. It came with an original hercus? dividing head but there is only one dividing plate that has a variety of hole circles on both sides. My google readings indicate there were 3 plates in the set.
My question is , can someone who has been down this road point me in the right direction of a web sites or perhaps a machine owner to find out a) if the 3 plates were double sided, b) what were the number of hole circles on each side of the 3 plates. thanks in advance, cheers Ian

The plates have holes on both sides.
I will get back to you with the hole count.

Plate No1,15,21,24,27,33/17,19,23,29,39
No2,16,20,31,41,47/18,25,37,43,49
No3,28,35,51,57,63/32,36,53,59,61
