What you have is a step back in time.My guess,early to mid 60's.Before the Gun Control Act of 1968.
Magazines likePopular Mechanics,and all gun mags had ads where anyone could order milsurp rifles through the mail from Klein's or other outfits.IIRC,a 98 Mauser was$30 to $50. A Garand was about $80.Mostly folks joined the NRA and got a 1903 or 03A3 Springfield for a very reasonable prices .
Fajen and Bishop sold stocks I still have an old catalogue. From Brownells,you could get Mark 2 safeties,as yours has.Bases,rings,etc.
Your friendly crotchety local gunsmith was good for parts and services.
Among the common folks,some shop skills and the DIY spirit were strong.
It was common to strip and clean up a military rifle,buy a 98% shaped and inleted stock,etc. You might pay the smith to alter the bolt handle,drill and tap for scope,and blue it.
A lot of folks had wood shop and could sand and apply Tru-Oil or LinSpeed finish
Some of these rifles were built start to finish by a smith,but most were home built by a hobbyist with some help from a smith.
Which means about anything is possible,not all of it good.
Maybe the work was done right,maybe not.
Stock inletting ...recoil lug,flat even floor,mag box height right,etc...it might be right. Many are not.
It does appear to bean original barrel. Folks did not do extra work to step the contour! Replacement barrels usually were not stepped.
It might be original 8x57. Sometimes people reamed out the chamber to 8mm 30-06. Some rebored to maybe 35 Whelen. You just do not know.
So let a smith figure out what cartridge it is,check headspace,and see if the wood is mostly fitted right.
IF your smith lets you know what ammo to shoot and declares it safe and sound ,you have a hunting rifle. Enjoy!! Eat venison.
Value? Its worth what someone will pay,really.Market is not great. No put down intended..bottom end maybe $150,top maybe $250.I'm not an appraiser.Thats a guess.
But it will probably hunt as well as a $500 rifle.
