Riverside Arms 16 gauge single shot shotgun with no other markings other than the number 60002 engraved inside the forearm what can you tell me about it?

Answer 1

The only reference I have for Riverside Arms says that they were made by Stevens, J Arms (who are now owned by the Savage Arms Co.). Riverside Arms was probably a trade name for one of the large wholesellers operating during the early 1900's. The fact that the gun has a s/n implys that it was indeed made by a major manufactor (many of the low cost guns of that era did not), which reinforces the above reference.
