The “G” stamped on the shank bottom might indicate a “giant” and maybe not…it’s certainly large enough, with a chamber diameter large enough for me to insert my thumb. There is also an “O” on the shank, perhaps indicating the treasured oil cured Radices.
The rim and the chamber are in very good condition. The stem is an acrylic replacement and there are little indents right on the button, top and bottom. I don’t see them having any impact at all on how the stem feels in the mouth or how it functions.
