Winchester 1897 Trench gun. Identification/History

Hello All.

Here is my 1897 Trench gun. I am in love with it and purchased is about 15 years ago.
I am starting to research its long history in the military. I believe it came to Canada from a batch via Korea.
I have dated the serial number E 679xxx to 1918 but believe it could have been earlier.
Has Flaming Bomb and cyl along with PW stampings.
Has this been refurbed for WW2?
Is is possible it saw service in WW1, WW2 and Korea.
Does the proof on the stock WB indicate WW2 refub? Is the stock original?
Are there any other markings I should look for?
I love this shotgun and want to respect its service history...

You have a WW1 made receiver (probably late 1917 or early 1918 mfg), but the buttstock with the WB cartouche is a WW2 buttstock. The original finish of the gun would be blued. If it does not have a re-arsenal mark, then it's anyone's guess as to who rebuilt the gun.

Interesting old solid frame though.

I have the brother to that gun with a 679 serial number,and same parkerized finish and same WB cartouche. I would love to know more about these guns.

You'll need to post pics because that guy hasn't been back since he asked that question...

Will do if I can figure it out

Worst case, you can email them to me and I'll post'em up for you here. Email addy to your PM...

If you’re still willing I would love to send some pictures of my gun, it has the same finish as the gun pictured. With a WW2 stock and military markings on the receiver, thanks.

Always willing...see PMs.

Here are the pics of his shotgun...'97...
