Yes, the Legacy has a wider FOV than that of the Zephyr. Sorry about my typing error. I don't have the specifications, but I recall that the 7x35 Legacy's is over 400 feet at 1,000 yards (maybe 420-430 feet), whereas the 7x35 Zephyr's is around 367-375 feet, if my memory is correct.
If the choice was mine, I'd go for the Zephyr.
Getting back to my comment on construction quality: When the Legacies were sold in the 1990s, which was toward the end of B&L's marketing of binoculars, B&L had roughly three lines of binoculars: in descending order of price and quality, the Elites, the Customs, and Legacies. I think there might have been a few more models in there, but as 'series' or 'collections' of binoculars, I think that was it. So, the Legacies were the low-end line. In contrast, the Zephyrs were sold in the 1950s and 1960s, I believe, and were top-of-line binoculars; I don't know if B&L, then, offered lower-end binoculars. A few decades and levels of quality apart between these binoculars, as I see it. Zephyrs were made in Rochester, New York, and the Legacies were made in Japan.
One other thing, being of the vintage I mentioned, the Zephyr probably has a slight yellow bias in its view.
