So why do my supposed "PJ 38's" have PJ 32 stamped on the sides? The outlet side measures 38 mm. I also have a set marked PJ 30 that measure the same. WTF?

Mine say PJ25... but I suspect only PJ is relevant, the rest is serial number or manufacturing number.

My PJ38's are quite early. Logically I would say the higher the number, the newer the type. Differences are generally in bypass design and other minor internal differences you can't necessarily see.

Yes I have sets marked PJ30 and PJ 31, identical other than some internal mods

They are called PJ38's because they are a PJ carb and 38mm diameter.
PJ36's are a PJ model carb and 36mm diameter and so on...

My '38's are marked PJ 29.
