This is a Vintage Kaywoodie Super Grain 12B Pipe.  The chamber is clean and has seen light-moderate smoke.  The exterior bowl looks good for age.  The bowl rim looks good, it does show some light burn on inner front and inner rear of rim.  The original stem with 3 howl stinger has good color and screws firmly into the shank.  The bit/lip look good with light wear.  Airflow is great with this pipe.  Pipe identifies as KAYWOODIE over Super Grain over IMPORTED BRIAR on the left upper shank and 12B on the right upper shank.  Please see all pictures and let me know if you have any questions. I do combine shipping.  When you are done bidding, let me know and I will send invoice with a discount.
