This pair even comes with a 50 kg granite stone slab (and an "interesting" claim about it's properties)!

A Pair of Altec Lansing Model 19 incl 416 8B 811B 902 8B Near Mint | eBay

Interesting configuration by the way--alnico woofers and ferrite h.f. drivers--maybe manufactured during their transition from Alnico to ferrite? (or maybe replacement drivers?).
