I would add that being a great fan of the older classic cars and particularly focused on the Duesenbergs that any of these listed kits can make great conversion pieces with some research and effort.
Model Martin's Mudd coupe is fantastic as is the stock Duesenberg hood he created. I have an order in for 10 of the stock hoods for already in progress Duesenbergs on my desk. The stock carb, air cleaner and stock exhaust can be cast from one of Art's old Duesenberg stock hood and accessory kit or from a Franklind Mint Gary Cooper yellow Duesenberg.
I would be a candidate for any of the reissues or new classic resin kits.
