But irrespective of the cause, the effect on my collection is that I have very few US-produced Stunters: one polythene Mk I and one ripstop Mk II. And that means I was very glad to be able to add a ripstop Mk I, in very good condition, to the collection!
Orange sail and, unusually, a purple tail. Original as far as I can tell, and the first purple PP tail I've come across.
Kite flies as you would from a vintage PP, as you can see in the video of its maiden flight (or, to be more precise, its maiden flight as part of my collection). Struggling a bit whenever the wind dropped, but mostly happily flying around, dragging its shiny purple tail (which, for some reason, refused to inflate):
