Part 18 of an occasional series about rings in my Etsy shop that remind me of things.

Ring:

Thing:

1:60 scale wooden model of a screw propeller of the SS ‘Great Britain’, the magnificent and innovative ship designed by Isambard Kingdom Brunel, and built in 1843. The ship is now a museum exhibit at Bristol; this model is in the Science Museum in London.
