Well considering that moore and kling inc. is a water utilities company in Mass. It is more than likely a device to regulate the flow of water through a pipe. the lever starts vertically, then can be rotated clockwise all the way around back to vertical for 100 % flow rate.

did anyone notice the conversion mistake on number 7? 379 feet = 115 meters, not 155.

other than that, great post.

Thats ridiculous. Don't tell me what to do, and much less, how to vote.
