Bridge Gun Company and Bridge Gun Works were trade names owned by Shapleigh Hardware Co of St Louis. The guns were made in Belgium by H. Pieper and Anciens Etablissment Pieper and in the US by Crescent, Stevens, and Harrington & Richardson. There's a good chance that a single shot would be a Stevens Model 94.
