Coast to Coast Model 267 20 gauge according to Proohouse.com is the Savage model 77; however it looks like a Remington 870 clone to me. Ron Montgomery rgmont@verizon.net
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.
Proofhouse.com has a store brand conversion chart that might help.
I am pretty sure that it is modeled after the mosberg. That is how i order parts for mine.
Mossberg.
Coast to Coast is a trade name. Marlin, Stevens, Savage, Mossberg and Springfield all made product for them.
toy's R us I can't match the Coast to Coast mod 660 however Savage, Marlin, Stevens, and Mossberg all sold various models to Coast to Coast and all of them made a pump shotgun. One of these manufactures likely made the mod 660. Find a Gun Values book and try to match the model to the photos.
