John- Welcome aboard. Can't tell you where to get new logos, but as a restorer of a 1965 McKenzie Cherokee Playboy, I know there is now a special section of iboats dedicated to Cherokees. At the bottom of the "forums" page there are brands of boats listed in alphabetical sections. You will find the Cherokees under the "A-C" section. There is a little info there, but keep your thread here for lots of traffic. There also has been a brochure for 1959 Cherokees on ebay for some time if you have an interest- it is not mine, just thought you might find it interesting. Hope it helps you!
My 1965 did not have badges but decals, which I had my local vinyl guy recreate from images I found on the internet of the Cherokee logo. It took me quite a while to figure out that it was actually a Cherokee, they are fairly rare. Post as many pictures as you can as they will help others indentify their boats in the future. We love pictures!
