VERY NICE BRONZE SPOKED SPUR GEAR APPROX 3.5" dia 24DP 1/2" bore Steam Engine

Here we have a very nice Bronze or Gunmetal SPOKED GEARWHEEL.
It is just over 3.5" diameter, 1/4" wide across the teeth, and the boss is bored 1/2" diameter with a keyway machined through as well.
The gear wheel has 84 teeth spaced at 8 teeth per inch and I am reasonably certain it is 24DP, meaning that any other 24DP gear will mesh with it regardless of diameter.
This would be superb on a stationary steam engine or beam engine crankshaft to transmit the power.
The proportions are just right.
The quality is excellent and you won't be disappointed.
Thanks for looking
