Zephyrs are indeed great horns, however be aware that a bit if time after the introduction of the Super 20(which began production in 1945) and Super 20 Silver Sonic(1949) models, the Zephyr was relegated to the ranks of a student line of horns( Even though the early S 20s are little more than more elaborately decorated Zephyrs!). As a matter of fact, actual Zephyr and Zephyr Special models ceased prodution in 1945. Your horn would actually be a Zephyr II. This did not impact the quality and construction of the" Zephyr" horns through the late 40's ( they were still being well crafted) but by the 50's, the this model began to show signs of cost cutting and simplified construction. By th mid to late 60's, both lines of King horns started to slip drastically in quality/features until they were discontinued all together by 1975. In other words, a King Zephyr from 1940 is not the same animal a one from 1953, and should be valued accordingly. Having said all that, and set the record straight, $400.00 is still a good deal, provided the horn is in good condition. Cheers and good luck.
