I wonder if 1343 might be some manner of steam whistle and/or relief
valve...possibly actuated by pulling a string tied onto the ring.


The owner got this device a long time ago and has forgotten exactly where it
came from, he is a licensed ammunition collector so it may have been in a
box of things given to him at one stage. He tried blowing through it but it
didn't make any noise.

I sent an email to a steam whistle collector to get his opinion but haven't
heard back yet. I'll let you know if he confirms this guess.
