Well well well.
Cheektowaga was the home for Buffalo Arms.
Buffalo Arms was created by Houdaille to manufacture aircraft machine guns for the Brits.
At some point after the US got in I think they made other versions and later also produced M1 carbine barrels.
With things winding down in 1945 the production equipment was mothballed or sold and the building and land was sold to AMF.
Not sure when AMF closed that facility. If you guys or your relatives have any info on it, let me know.
