I just bought 20 sq of 20X14 used Buckingham. They were 250 slates short of what I needed so they gave me for the same price 250 16X24 used Buckingham. Must have been custom made for some one, ea?
I was about 30 short, had to use 14X24 to finish. Cant even tell the difference
I have a 150 or so 16 x 26 Bucks. Come in handy for repairs at $50.00 each, plus the service fee, of course.
