This corner of the exhibit shows a number of manufacturing tools:
Most of the tools in the exhibit originated in the New England area from two companies. J. R. Brown & Sharpe of Providence, R.I., and Waltham Watch of Waltham, Mass.
Here are a few pictures of the machines close up.
There is also a nice sample of gears, presumably cut on a gear-cutter similar to the one shown above.
