Alex MacKenzie throws some light on the operations at the Hill Shops.

In the late 1880s, the Armory constructed three new buildings in the then vacant area called 'Federal Square'. (East of the Armory Square complex).

The Stocking Department, Milling, Machine and Filing Shops were located in these new structures. Those overhead pulleys were powered by stationary steam engines, located nearby.

It is in this location that much of the work in manufacturing the Krag rifles and carbines was done.

(Federal Square is now the site of the Springfield Technology Park and it would appear that some of the Springfield Armory structures have been repurposed for 'high tech' companies).
