Greetings

Please help me identify this shotgun. I have taken a bunch of pictures.
A gun shop owner of 35 years couldn't id this gun because it was too old.
I took pictures with some glare on purpose in some cases to make the markings
stand out. The gun belongs to my neighbor who's a WWII vet. He's interested in selling it.

Here's all the markings I can make out from looking at it:

MANUFACTURED BY THE
WINCHESTER REPEATING ARMS CO.
- NEW HAVEN CONN. U.S.A. -
PAT FEB. 16 & JULY 20 1886

SERIAL # 48619

One side of the gun has a design with R A 0(zero) in the middle of a circle covered by a large cursive W

You can clearly see all of this in the photos below.

If you can ID the gun and give an approximate value and
maybe a place to sell the gun in the Seattle Area you'd be helping a Vet. Thanks!
