Exhibition mica diameter?

[jboger]

OK, I searched under "Exhibition mica diameter" and found interesting discussions of the pros and cons of Exhibition reproducers vs the No. 2. But I'd like to know the diameter of the mica used for the Exhibition reproducer. I'm about to place and order with Brian (the phonograph shop) for a number of items including this mica, but not sure which one to order. Any one know off the top of his/her head?

Brian came through! I will now place the order.
