I remember back in the early 1970's Remington made a plain jane Model 870 they called the AP Grade.Perhaps it is one of those models.Cannot remember if they were marked AP Grade on the shotgun or not.
Just looking around and I found an old Remington flyer from 1972 that lists the Model 870 AP Grade.No checkering and groved forend.A bit of an extension at the back end of the forend.Plain barrel version $109.95 and vent rib $142.95
Not too sure on the year, but that is pretty desirable furniture.
Wood is wood. "Furniture" refers collectively to the small metal pieces like sights, trigger guard etc.
There you go so much for my old memory
Update
Interesting even the blue book says 1963 sure that flyer is not 62???Put your glasses on you old fart
MODEL 870AP
"Wingmaster," 12, 16, or 20 ga., 26, 28, or 30 in. barrel, 5 shot, various chokes, plain pistol grip stock. Mfg. 1950-63. There is pricing information available for purchase for this model.
1963
Remington produced the Model 870 in a new deluxe grade for all field models with custom checkering and improved wood finish.( That was the new fleur de lis)
Who you calling an old Fart.LOLProblem is ,you could be right, Mac.LOL I remember looking at one of the AP Grade Remingtons back in the early 1970's.Was going to buy it or a Winchester Model 2200.Bought the Winchester Model 2200 at the time.Poor choice on my part.
The flyer was in a 1972 catalogue along with some other flyers telling of some other Remington products.One was the 10 C Remington .22 auto loader.
That's the forend pictured on the ad I have from 1972 for the AP Grade,Mac.
