What's the chance this wood is correct with no checkering?
The forearm doesn't have quite the right shape.

Plenty of dings and nicks appropriate for a gun that has been hunted and handled for a long time. I did not get the serial number for it yet.

Other than the 1899 250-3000 Rifle pg stocks, all of the other pre-WW1 1899s with pg stocks have had the distinctive curve, "wave", shape on the bottom of the pg. This is the same design as the early Marlin lever action rifles with pg stocks. I can't exactly tell from the picture, but the bottom of the pg appears to be straight, rather than the curve/wave shape.

I have around 80 1899s with pg stocks and all of them have the curve/wave on the bottom of the pg.

That's what I was wondering. Can't tell if it is wavy or flat.

Can't see the tip of the forearm. D&T'd. The rifle is pre-90,000. Fancy walnut with no checkering was an option.

Bottom of the grip does have the marlin wave, check.

The end of forearm has the delicate schnable, check.

The bottom of the forearm has hard corners, like the bottom of the receiver, for about 4", that's one of odd looking details to me.

I need to call them back and get the serial number and barrel address, it's 303

I'd guess it's original, just refinished.

If you enlarge it enough you can see the Marlin curve.

There is info on the tag. SN looks like 45.703

The bottom lines of the forearm look very angular in cross section. You think that maybe someone got a little over zealous with sanding when they refinished the factory stock? The back of the pads look like they may have been "home brewed" too.

Given the added scope, I'd cast my vote for a stock refinish from way back. Possibly the late 50s or 60s. Hey, wait a minute. That makes me from way back too. Crap!
