Looks like you have the premium model with the adjustable grill height lever. I like the interior ash catcher they use too. Be sure and show us it all cleaned up and your first cooks too!
No need to feel foolish, they’re really cool grills. They’ve got some neat features and I’d imagine are pretty rare being as they were only made for a short time. Get some wheels for it and cook on that awesome grill!
Welcome from PA! Cool grill looks like a Happy Cooker, very similar to Weber.
Here’s some info that Chris A. posted awhile back about them.

@Josh Dekubber This is a great book to have, tons of info about every GPA that Coleman has made. Nothing about mechanics or restoring, just history and how to identify different years that aren’t marked.
I like the little single mantle 200’s a lot, much easier to work on than the 220’s. Here’s a ‘61 with a cool handle/reflector and original amber globe.
