When the original Toker II came out ( early 1970’s) it only had one hole for the stopper and stem. It was a pain in the ass to pull up the stopper to “carb” the smoke out. Enough of that so, I drew the Toker II with a small hole where the little stopper is on the new version. I sent the drawing to them and said I didn’t want any royalties ( I must have been very stoned D’UH) or anything, just make it the way it’s drawn for easier use. About a week later a UPS package came with the first carbureted Toker II and a nice thank you note. At that time there was no little stopper supplied with it. I found one and sent them a note with the size and number. I still use it to this day!
