Remington didn't begin making carbines until 1960. Any carbines of earlier manufacture are rifles that the owners had the barrels chopped on. 760 Carbines say "760 CARBINE" right on the barrel. If it doesn't say that, it's a chopped rifle. The guns with the dropped combs and slide bars are pre carbine era.
Hah! What a timely post. I was beginning to think that was exactly the case.
I went to look at a 1955 760 today. It was advertized as a carbine. The owner had sent me several pictures, none of the "760 CARBINE" on the barrel however. When I quizzed the owner he said "Well it is a 18 1/2" inch barrel. It had been chopped. I walked away and found your post on my phone as I was driving away. Thanks!
Thanks also for clearing up the time frame frame for the dropped comb.
I am still looking.
