Mossberg.
Take off the buttplate. There is a screw inside. You'll need a long screwdriver and a flashlight.
I am pretty sure that it is modeled after the mosberg. That is how i order parts for mine.
To the best of my knowledge (and I was once told) The coast to coast shotguns were made by Mossberg. Master-mag is the coast to cast house name brand. The evidence I see that Mossberg was the manufacturer it the thumb slide safety.
Store brand name
Mossberg
Got one -- what are you wondering?
You will need to provide more information than that. I have never heard of a Coast to Coast shotgun, even as a trade name. I think they are Master Mag which I have heard was an in store version of the Mossberg 500. Coast to Coast is the store it was sold at I believe. The above is correct. Coast to Coast was a Hardware store which sold various guns. Mossberg manufactured guns for coast to coast to sell. Coast to Coast relabeled these guns with their own model names. The CC 660 was the same gun as the Mossberg 600 which is now similar to the current model 500. Roughly worth 200-250. The one thing I'm not sure about is this. There are several variations of the model 500, but which variation was used to make the cc660. So again with that said, 200-250 USD.
100-200
It was made by Savage for Coast to Coast. It is a Savage Model 58.
