The company is listed in the business registry through the years 1911-1918 with a C.F. Runch as president. All those regitry lists name the st National Bank Building as its office place. The phone number may indicate a more specific time period which may be later than 1918. Nice find

§ 91. A short history of telephone numbers If this link will work, it will give you a history of the phone numbers. I believe it says yours is early 1940.
