Hi Aaron-
Congrats on a very nice Model 70.  That's one to be proud of and hang onto for Generations.
To answer your question.  Model 70s did not have factory drilled holes on the bridge until 1946.  So the (probably just one) hole in the bridge for the rear of the Redfield JR mount was added.  The other holes, two atop the front receiver ring and two on the left side rear for a receiver sight, were factory.  Your rifle was originally a G7003C (Standard rifle, 270 WCF, Winchester 22G Sporting type rear sight).  So the only other "alteration" is that the rear sight was removed from the barrel to allow clearance for the scope's objective bell.  As best I can tell, everything else, including wood and metal finishes, is original and correct.
The scope is a 4X Unertl Hawk and it's in period Redfield rings. Those scopes date to about the late (post-WWII) 1940s or 50s.  Your Grandfather certainly knew quality, as that scope was about the best available at the time.
For comparison, the one pictured below is also a 1936 vintage Model 70 Standard rifle (s/n 1099).  It's a 30 GOV'T'06 but otherwise looks like yours.  It has the type of rear sight that was removed from yours.

Hope this helps,
Lou
  

Thank you, Lou! That’s extremely helpful and I really appreciate the kind words about my grandfather.

 Ill comment on a couple of things i see until our experts roll along
 First and foremost (In my opinion), Do NOT do a thing to this rifle except wipe it down gently and shoot it at every opportunity including take it out and hunt it. You only get a couple of chances to own something that was your grandfathers. He obviously shot the rifle a fair amount. Truly a wonderful heirloom.
That being said the rear bridge has been drilled and tapped for the scope install. Many of them were and some of us feel that it was a shortcoming of Winchester to not do it on all of the early model 70s.
 Maybe the finish has been touched up a bit. this would be normal for a rifle that was hunted here in the Northwest.
 All in all a very nice piece. Please enjoy and respect it for what it is.

Thank you, Doug. That’s certainly my plan, keep it clean and shoot it when I can. Appreciate the insight. 

Anybody have one?

Recently, my father passed away and I inherited all of his guns, including those of my grandfather's. Part of that group is a gorgeous Model 70 in 270 WCF, serial #2047 (there's also a 243 Featherweight that I got my first deer with and a beautiful Model 52 which shoots like a dream, but those are for another post). From my rudimentary research on the interwebs, I've determined it's a first-year 1936 model in a very popular caliber. I took it to the range at my gun club the other day and it took me right back to when I was 12 going out with my grandfather on the first day of deer season. Anyways, I was hoping some folks on here could help with some questions. Would the scope have been original? Does it look like he modified it in any way? I know my grandfather (32 at the time) would have bought it new at Dunham's Department Store, but I don't know how it would have looked then. 

Any help would be greatly appreciated. Hopefully, these pictures are helpful.

More like a brain fart, sorry chaps the sn was 7749**. 
  

That is a common affliction!!  The SN is not early by any stretch.  Here is a section of my spreadsheet which shows a large batch of DCP marked carbines.  I have SN 774965 as being in Australia.  Maybe that was your rifle?

Michael, good to see my DCP 1892 is marked 'Very Nice' in your survey 😀 
  

Chris,

The bluing on the receiver is worn a bit  but over all the rifle is crisp and has been well cared for.  The majority of the other DCP guns are fairly well worn.

In more scientific terms, we call it a "Cognitive Glitch"

Tony, check out this pair. My 1892 DCP SRC and extremely high condition 1894 DCP SRC - the earliest known in Berts survey.
