Hello my Friend, from the article, it looks like at least one was sold, one was kept by Crosley, and possibly one was sent to Crosley's friend Commander McDonald
The set was priced at $1,500.00. There is no record of how many of the WLW Model Super-Power Radio Receivers were built, but the first sale was made to Wheless Gambill — a Crosley distributor in Nashville, TN. Powel Crosley, Jr. certainly put one in his home and probably sent one to Eugene MacDonald at Zenith.
