I have a bunch of cases from Hobby Lobby. I think they're from Pioneer Plastics.
1:24 scale Diecast Case - 9″ x 4-3/8″ x 4-1/8″ - 094c (pioneerplastics.com)
I also have a wall display case.
Thanks, Bob. I thought that maroon was appropriate for the year of the car. The Stovebolt Car Club plaque comes with the kit, and I thought it would look good on a "restoration".
