Great job. I don't think those seams are too bad. It's a very common occurrence with that era of wrapped shells -different glue that tended to shrink over time and pull the wrap with it in the process. I think you could probably re-glue the seams or get them professionally re-glued if you aren't sure about doing it yourself...or just leave them if they aren't curling up. The wrap looks nice and white so it probably indicates that the drums were kept indoors in a shady room...probably a hobby kit that didn't get played too much.
They are definitely a matched kit with those serial numbers in sequence. The Supra looks pretty good (you would be surprised how well they clean up!), so I would keep it with the rest of the kit -unless you have another one in better shape with closer sequence serial numbers...Burger Kin
The only criticism (if you want to call it that) I would have, personally, is with the larger sizes. I am a jazz drummer and I prefer the smaller sized shells...but like I say...that's just me.
I think you did very well for that price to get a matched set of 3-ply vintage blue and olive badge (the pointy ones) Ludwig drums in WMP that seems t be very white.S/H is probably going to be a bit pricey because of the larger sized boxes required to pack them.
Let us know when you get them and we'll take a closer look!Burger Kin
