Doors very rarely come up for sale, but it could be an fun little project making one yourself 
That thought does have some appeal to me Jan, I like the Idea of scale the Wilesco design down to fit a smaller engine properly. I see a 3 piece pattern in my head that would allow me to practice my much needed Solder skills...I also see a 1 piece pattern that if carefully cut and folded would allow me to get quite close to the Wilesco look. Thanks for the input!
