Anyone out there ever heard of "Kankakee Clay Partition"? They are clay building materials that are throughout an old (mid 19th century) barn building a group I'm part of is looking to purchase in Peoria, IL. There's a town called Kankakee not too far from Peoria but so far I haven't had time to do much digging beyond the internet.
The pieces appear to be extruded blocks where stacked one way you see the sides and they look solid but stacked the other way you can see the open structure. I can find some pictures to share if it would help anyone out.
Thanks.
