I agree, John, a little too high, although they appear to be kept in good shape by the original owner. I don't think they are actually taller than the Barcelona's, just not as wide, as they house the 811B horn, as opposed to the wider Barcelona's 511B.
If you can find a mint pair of either Granada, or Barcelona with a good working 770 biamps, they may be worth that price. Big "if", though.
