Here is a Speed Indicator patented by Greene, Tweed & Company November 22, 1892.  The nickel plating is intact, and the attached bell rings every 100 revolutions.  The presentation box it came in is labeled "With James Kowden's Compliments" At this point in Greene, Tweed's long history (from 1863 to the present) they made tools, graphite packings, hammers, cast brass hinges and drawer pulls, speed indicators, and coal furnace clocks.

First one I've seen , Nice piece

Great piece, Bob!
I like to see the old ones kept in good shape.

Don't know if I am more impressed with the indicator, ...or the nice box it came in.

Very nice :)
