From what I can see right now, someone has shortened the stock on it at the end of the forearm.

The Savage 1919 used to have a full length stock with a barrel band, it looks like yours has been shortened right where the barrel band would have been.

Also, the rear sight has been swapped with a Marbles, they pretty much just ground the front of the dovetail off and drilled a hole into the sight so the screw could go it.

I'm not 100% sure on the date but if sav22 checks in he'll narrow it down for you.

Someone is parting out an original 1919 on Ebay right now but the prices are getting up there.
