This is a Linkman's Dr. Grabow square shank billiard. No other markings. From what I've read, the "propeller" logo was discontinued way back in 1944. Barely smoked - just take a look how clean the stinger is. Birdseye on the top and bottom of the shank. Nice clean stem that lines up perfectly with the shank. The pipe is about 5.25 inches long, and the bowl opening is about .75 inches across. 33g according to the kitchen scale. There are ...two things I want to mention. First, although the briar is very clean, there is a very tiny, but noticeable fill on the edge of the bowl facing the back of the pipe. Second, if you look at the last photo, there is a slight forward cant to the top of the bowl. I presume that this is how it came from the factory. The finish matches, and I'd imagine that back then, nobody would have noticed or cared. Still, I figured it was worth mentioning. Sanitized and ready to smoke - any additional cleaning is up to you.
