Feb. 16, 1895 Sporting Life (Spelling is as written)
During the past three years on visits to such sporting clubs as Larchmont, Carteret, Tuxedo and Riverton, we have noted the peculiar fact that out of 20 or 30 guns on the grounds at one time there will possibly be one gun of American manufacture. All the others are “Crown Grade Grenier's,” “Premier Quality Scott's,” “Purdy's” and other foreign makes.
The remarkable state of affairs, which is not creditable to American manufacturers, would indicate that there is something lacking on their part. We know that men with “hobbies” are willing to spend much money to gratify their “hobby;” but we are not willing to concede, if only from a patriotic sense, that American manufacturers are unable to satisfy their countrymen's “hobby” in guns.

Some Facts About the Retail Gun Trade - The Mania For Foreign-Made Guns
Parker Bros., of Meriden, Conn., are producing a Special high grade pigeon gun which is certainly equal to an imported gun in every way, and best of all, the shooting quality is not lacking.
The Hunter Arms Co., of Fulton, N. Y., also make a special gun which is finely finished, perfectly balanced and contains the best workmanship.
The Lefever Arms Co., of Syracuse are also catering to this better class of trade, and have already filled many orders for guns costing $300 to $400 which were equal in material, finish design of engraving and general workmanship to any foreign gun costing much more money.

The "buy American" campaign, and the price differences, must have worked.
