Eureka! I found this passage in a review by Art Friedman on Kawaski and Suziki sharing the same model of cruiser.
"Though selling the same basic vehicle under two brand names has become common in the automotive world, the practice is a comparative rarity in the motorcycle market. A few Royal Enfield vertical twins were sold as Indians in the 1950s. In the late 1960s, Laverda 750 twins and models other from other makers were sold under the American Eagle brand in the U.S. Evel Knievel even rode one for a while." Guess I wasn't "incorrect" after all. VWW
