I picked it up off ebay awhile ago and its been sitting on a shelf in my garage....i've tried to describe it to a few people and they were unsure.

its obviously a race nozzle of some sort.....but its not the typical berkeley one. It is longer and doesnt have the mount for the rudder. its about 8" long and has a casting number on it of "L-2847"











i figure its some knock off of the berkeley race nozzle.

Looks like a stepped snerplewizzinator with a flarery outy endy thing.
Just my opinion. LOL  Short potato gun? Butt trumpet?

LOL!!!

beerjet is half right, someone added the round tubing on the end, part # L-2847 is a old standard nozzle housing from a early berkeley, that was cut off and the tubing welded on,  Jim

... Odds are it's some prototype part off Rasberry  .

yep
