Look at www.greatmodels.com click on "database" search for "1/48 kyushu"
They show a Falcon product for $13. I can't tell if they are vac canopies, vac masters, or what? Call Great Models. They should be able to tell you?
Hope this helps.

Did some surfing. They are vac canopies. Falcon, for the most part, doesn't sell single canopies. They sell them in sets of half a dozen or so differnet canopies.
