Check with a local gunsmith. Parts from a J. Stevens single shot should fit. Numrich may also be able to help you.
Numrich Arms (GUNPARTSCORP.COM) lists several parts for the Stevens mod 94 in different gauges, depending on the exact model.
Without the model number, it will be difficult to get you a price. However, you can go to www.e-gunparts.com to order almost ANY gun parts you need.
