Hi Ron,
I've never seen the compass equipped Zeiss 7x50, but apparently it did exist, at least for a little while. The US price list below is dated January 1, 1993. Maybe Gary or Jan can tell us more about it.
Seems odd that the list pice of the 6x42 Dialyt was about the same as the 8x56 and substantially higher than the 7x42.
