It's a Rem 700 BDL, and I can see some areas of the stock finish has shrunk a little into the grain, so it's probably about 25 years old or so. Maybe you can date the serial number if you contact Remington. As of the peep sight holes, if I remember correctly they came that way from the factory, but it's been years since I held one of those fine rifles new.
It was common in Southern Ontario to put new heavy weight barrels on varmint caliber rifles. Mostly, they were barrels made by Douglass and installed by local gunsmiths. Some people did not bother to stamp any info on the barrel for some reason. You should look under the barrel by taking the stock off. Maybe the info was stamped and when the barrel was turned on the receiver it positioned under the wood.
Be interesting to see if the stock has been glass beded at the chamber. Also, if you get the chance, have a gunsmith check the head space to see how tight it is. This will tell you it was a barrel change and most likely done professionally.
