Balsa USA kitted this model in the 80's. It is considered giant scale but forgot exactly how big. I think you can still get the plans from BUSA and then I am sure there is a kit cutter out there that could help you out if you want a kit.

Here is the link to a kit http://www.lazer-works.com/misc.html
not sure what to do for plans. BUSA did not list them on their site.
