This is a Grp. 4 in Peterson shape #221. The bowl and chamber are in excellent condition, having been barely smoked. But the original owner must have liked to hold it in his mouth with his teeth so there are very light tooth indents on the top of the vulcanite stem and one distinctive, but shallow indent on the bottom of the stem. The draw is open. The nomenclature is a little light, but that appears to be the result of the original stamping and not due to wear or buffing. The "P" logo on the side of the stem is fully intact.
4.9" long, bowl 1.75" tall. Weight: 1 5/8 oz.,, 47 grams.
