yes, the GoldStar wands do have rivets holding on the plastic lips, not the best design I'll say, but the inside cavity was wide enough that the rivets don't appear to catch much.
These particular two wands were purchased from a Canadian distributor who had traveled down to Ohio to meet the GoldStar welder who created the wand, he was never a carpet cleaner, so it's kind of amazing he had so much vision, the adjustable jet on the 10" wand is pretty cool, as is the jet it's self, it has two orifices instead of just one, think of the edges of the jet being cut instead of just the center, it has a super wide spray pattern yet is fairly low to the carpet, he also pioneered the water hitting the
glide before the carpet.
Just as cool was the ServiceMaster glide from the 80s.
