So I picked up this piece from a buddy. The piece is a phx recycler, however he said the fritted disc was a David Goldstein disc. IMO it doesn't really look like the dg fritted disc I've seen before. It says "blown in California" on the back of the stem along with a patent number and serial number which he says is for the dg fritted disc perc. So does anyone know anything about this thing? It hits like a champ but clogs super easy with wax. More of a flower piece. Thanks for the input. Sorry about the low quality photos.
Looks interesting it has a male joint so I assume its made for concentrates but a flower recycler might be a cool idea.
Just look up that patent number and see what it is for. That's the point of having an assigned number
