If I could do so, I would have done so.
Looks like a 12 foot table to me.
(Unless the camera used a distorting lens, ain't no way IMO it's a 9 footer, this beast looks like a football field. Do you see how small the 15 ball rack looks in relation to the table?)
I think it is a ten foot table, but not 100% sure. If it is, how much do you think it is worth? 1894, 1.5" thick slate. Thanks!
I neither have access to the table nor the owner, thus I am unable to measure it.
