i got in some 510 attys that i bought from another member here on ecf i was wondering if anyone could tell me who makes them or give some info on them, normally i get joye attys but the deal was good, i assume he bought a ton wholesale and was selling off extras. looks like a standard 510 atty but when you look down into it there is a metal ring around the bridge, and the airhole is not on the threads like im used too it's under the cup of the atty (best way i can describe it. it performs well just makes a weird gurggle/whistle on my ali'i and i assume its cause of where the air hole is and it being in a weird spot on my catch sup. anyways, sorry no pics, but wanted to see if i could gather a little info
