Byron is the manufacturer you're thinking of, now owned by Iron Bay Models, at http://www.ironbaymodelcompany.com/

They haven't re-released the kit yet, but still show it on their "Aircraft" page, and may have parts, plans, drawings, etc..

Also, here are the results of a "Google" search I just did for you, at http://www.google.com/search?hl=en&i...ft+Staggerwing

Happy building!
