Benroy Teardrop Trailer - $950 (HORNICK, IA)
In looking at it, I think it's a later edition made by the King Richards trailer service? Who knows but it's different from most of the Benroy's I've seen. Note, the square cornered windows and the ribbed siding.http://siouxcity.craigslist.org/rvs/3032700279.html
Looks to be mostly there.
Not sure why I typed "Fitzpatrick" earlier. Edited to remove that goof. Fitzpatrick was the name of the company that Bennet worked for when he made the first prototype in 53, as documented here: http://outbackteardrop.com/benroy.html
That's what happens when you get old and only retain 1 out of every 10 words you read.
