Thanks for your reply RKC.
Just started a post on my recently purchased anniversary. When we removed the cloth we found a break in the corner of the middle piece. I've got it reassembled at our house now and it appears to have gone back in place tight and level. Any opinion of what type of slate this is?...TIA
