" I love the smell of napalm in the morning, it smells like........Victory!" That Duvall ?! As in Robert... 6sally6
When I was at So-Cal in San Dimus this summer they were doing some. Check So-Cal. Speed Shop San Dimus.com Just looked and they are showing Model A thru 36 Duvall windshields.
I recall Cam Grant in B.C. did them many years ago, business was called ?Past Tec? think he sold it but can't remember who bought it.
They sell (I bought one) a Hallock style frame. Completely different style than a Duval. To my eye, the Duval has the wrong line from cowl to top of the frame, in that it angles outwards, rather than in towards the center. It's called "tumblehome" in boat design, it just looks cool. It's all personal preference, I simply prefer the Hallock style frame.
I couldn't justify the expense of a real Duval, even if one could fit my cowl, so I built one from tin. Because I'm 6'6" tall I also had to make mine higher, even though esthetically speaking a lower one would probably look better, but functionality dictated such. Anyhoo, it was a relatively easy task to make a wooden buck and fab one off of that.
I got mine from Sellers and I think he sold the pattern to O’Brian. It came in two pieces and you have to fit it to the cowl and weld it the right and left sides together right up the center.
