Chokes and Chambers

[Researcher]

Or, was it chambered to shoot brass shells which did come in 2 1/2 inch length? What are the bore diameters?

P.S. 1891 was the year that Union Metallic Cartridge Co. began offering their loaded CLUB paper shells with the extra cost option of being loaded with American Wood or Schultze smokeless powders. While the price of the loaded shells varied from $23.50 per thousand for the lightest 20-gauge shells to $32 per thousand for the heaviest 10-gauge shells, the American Wood was $10 extra per thousand for 20- thru 12-gauge shells and $12.50 extra in 10-gauge. Schultze was $15 extra in 20- thru 12-gauge and $20 extra in 10-gauge.
