I just ran across this post. Brand new here, but a long term Willys Overland Knight Registry Member.
I am very familiar with sleeve valve engines from Willys Overland line of products. I own a '27 Willys Knight 70A cabriolet Coupe. In addition I own the one and only known 1933 Willys Model 8-88A. This car has been registered to the W.O.K.R. consistently since 1975 and I am currently the 5th owner. The Willys 8-88 was 1932 year model and there are currently about half dozen known, so still extremely rare. My 8-88A is currently under restoration.
