I'm not sure if you're still interested but I did a web search for sears ranger 410 and learned the following.
Ranger was a pre-WW2 Sears brand, they were built by various firms but mostly Springfield/Savage/Stevens.
Your 410 should have a model number that looks like 101.25 or similiar. Some of these are listed in the Gun Traders Guide under Sears.
I hope this helps
