I have no idea what you mean. Every Remington shotgun ever made was designated as a shotgun, and had a model name or number. If you clarify your question, maybe someone can help.
It's a model designation that Remington uses, i.e., Remington 11-87.
The 1100 designation for a Remington shotgun is the model number. Remington makes the 1100 model in a trap version and a field version.
Remington does not show a 870 rifle on their web site. Do you mean the 870 Shotgun? the Remington 870 is one of the most popular shotguns in the us. this shotgun ranges from $300 for the basic model to $1000 for the fancy Wingmaster edition
$20.00 to $300.00. I don't mean to sound sarcastic, but condition is everything.
Degree of choke
Did you a mean Remington SPR220? Remington SPR220 is a side-by-side shotgun. You can get a schematic of this fine shotgun from down loading the owners manual from Remington. Kathleen
I think you mean the model 48, no 40 I've ever heard of, and in typical lack of creativity for models in 1948.
I don't see dbl in Remington, if you mean the dbl in general when when referring to a Remington firearm that's double as in double barrel shotgun, derringer, etc.
Classic Deluxe
I am guessing you have a model 870. It is a edition of the 870 shotgun
Could be an inspector's mark, assembly mark, etc..
