No. Barrel marked as "R" "4-18". Receiver has "Remington" on top, under front scope base. So, is likely the receiver and rest of it made by Remington, not by Winchester or Eddystone. Bolt and cocking piece stamped "R", but has serial number on underside of bolt handle that does not match receiver serial number - headspace checks okay with gauges, though. Rear original sight ears have been ground off to be like flat rear bridge - home made rear scope base with flat bottom, that appears to match to Weaver #46 on front receiver ring. No provisions for iron sights at all.
Shooter's end of receiver does not appear to have been been ground off square - it still has the M1917 bolt stop spring seat in place.
