I only have one myself, it's the one on the bottom in this pic. As far as I know, they are a GBD sub-brand. Mine is a large, well built pipe that smokes like a champ! It's a little on the heavy side for clenching, especially since it has a Lucite stem, which is not quite as comfortable as vulcanite, but I only clench about 50% of the time anyway. I bought mine as an estate for about $25, a steal in my opinion!
