Can you tell if the repairs were done? Early Foxes sent back to Savage were often bored to 2 3/4" chambers and crudely marked as such on the barrel breeches.
It's a '37 Utica Sterlingworth so it was already 2-3/4". My suspicion is that the forend might be a factory replacement; it's numbered to the gun but it has an extra screw machined into the forward end of the forend iron and the workmanship on the inside of the wood is pretty crude; it almost looks hand-carved, although it fits well. I've never sent for a letter on the gun; I don't know if Savage kept any repair records at that time or not.
