I assume you are noting the aquisition of Hall by Barcalo...
Hardware Dealers' Magazine, Volume 41 (Jan, 1914)
"The Charles E. Hall Co., manufacturers oi the well-known Hall Tools,
have sold their business to the Barcalo Mfg. Co., Buffalo, N. Y.
The Hall Co. were located in the center of the city, and for some
time had been contemplating changing their location, when this
favorable opportunity ofiercd of disposing of their plant to the
Barcalo Mfg. Co., who- have a very extensive factory, where the tool
department will be given all the room and facilities required.
This will mean that the New York representatives, Wiebusch & Hilger, Ltd.,
will be able to serve their customers for these tools better than ever before."
(Wiebusch & Hilger was sales agent for Barcalo, and Lakeside Forge)
Hall was in partial receivership in 1912, I think they were in trouble for a few years..
Barcalo was at 225 Louisiana Street in Buffalo in 1918, and in 1936, So I assume they did not
move....
The Automobile 1907:
_ The Hall Carbureter.——
"The accompanying sectional illustration depicts the construction
of the Hall carbureter, manufactured by the Charles E. Hall Company,
Buffalo. N. Y., who are successors to the Union Manufacturing & Specialty Company.
In placing this carbureter on the market ...."
So, slightly before 1907
Hardware 1901:
"Buffalo, N. Y.—The Union Mfg. and Specialty CO., 506-508 Genesee Street,
have taken up the recently patented Bolton automatic tire repairing tool,
and will place it on the market. The inventor, G. W. Bolton, Jr., has
connected himself with the concern and will travel in its interests."
Doesn't completely answer the question, but a little closer, perhaps..
PS: re> I have a listing for Koeth Mfg Co. at that location in 1906.
Koeth was at 106 Broadway (1907, Automobile dealer & repairer)
