Spencer Repeating Rifle History

I was looking on the Internet for a history of the Spencer Repeating Rifle, specifically where it was made.  There is a very linked article on this that does a fairly good job of giving the history, but is misleading regarding where the first Spencer's were made.

For those that don't know, Spencer was born in Manchester, and worked at the Colt factory and the Cheney Bros. Mills.  At the Colt factory, he learned about gun manufacturing and took up the task of making a repeating rifle in an age of muzzle loading rifled muskets.

Anyway, the rifle was VERY successful, more successful than that Henry repeating rifle which was manufactured by some obscure gun company named Winchester...

In the history, linked above, it talks about how the first Spencer's were manufactured in the "Cheney Bros. Silk Mill machine shop, in Boston"

Anyone from Manchester knows that the Cheney Bros. Silk Mill machine shop is here in Manchester, CT, NOT in Boston, MA.  In fact, the machine shop is the current home of the Manchester Historical Society.  The confusion likely comes from the fact that the "armory" that was built to manufacture the Spencer rifle was in Boston, financed with Cheney Bros. money.

My guess is that the first Spencer's, the ones Spencer used to demonstrate and gain acceptance for his rifles, were made here in Manchester, rather than in Boston.  A small misunderstanding... but one that should be cleared up.
