The 1922MII is the most often found model of the Springfield .22's. The rifle in question was a 1922M1 that was upgraded in the mid 1930's or later with an M2 Bolt, M2 Magazine and M2 Stock.
On the down side is the shaping of the pistol grip and apparent sanding of the grasping grooves that keeps them from looking as crisp as when they were new. The front sight is probably a Lyman 17A. If so, it can be easily removed and replaced with the correct military post which is the same as is used on the 1903. They are very available and should be a $10 to $15 item. There were some globe type front sights that were installed by removing the front sight base band and replacing it with a globe sight. Hopefully the one on the rifle is a 17A or equivalent. The finish is not original. I would say less than 5% of the issue type 1922 series escaped refinishing.
On the plus side is the bolt being numbered to the rifle. When the M2 bolts were installed the rifle sn was etched on the bottom with an electric pencil. Some digits should be on either side of the joint where the front and rear parts of the bolt meet. The quality of penmanship of the numbering varied. If the number is in the proper location it is probably original. The barrel date would be correct for a gun with that serial number range.
The 125 on the elevation scale does not indicate yards. The clicks on the windage and elevation are 1/2 minute of angle.
The buttplate should be coarsely checkered and without a trapdoor.
I would think the rifle is worth the asking price of $975.00, even with the modifications mentioned.
A used unmodified stock will cost $250 to $300 if you can find one.
Sight inserts for the globe front sight are available. They come up often on the internet auctions. I think about 9 various posts and apertures come in a small metal container.
Spare M2 magazines come up often on the internet auctions. They usually go for $100 to $125. Avoid the aftermarket magazines as they don't have a good reputation for functioning. A correct magazine for your rifle will have a small M2 stamped in the top left side.
