The Receiver and Barrel SNs match. Early production 57XXX No asterisk on the barrel. The sight has different SN. The Safety is an Eddystone part.
The bolt is Winchester but the original SN on the top of the bolt arm has been peened out with only a few numbers visible. The rifle's SN has been stamped on the bottom of the bolt handle with a W following the numbers.
The metal has been through the WW2 Weeden Repair Standard (W.R.S.) rebuild as the rear aperture volley sight has been milled off.
Question on the Bolt. If this was a non * refurbished as an * would it have gotten a new bolt with change of numbers? Or could the bolt have been changed out during the WW2 W.R.S refurbishment?
The bottom wood is and Eddystone Fat Stock without finger grips. This was probably done by a collector as it still has the front volley sights. I will take advantage of that and have ordered a rear sight. One of the previous owner took care of it as it looks like it has been bedded a while back. I have not done a cleaning of the barrel but the lands and grooves are all visible for the length of the barrel and the barrel under the wood looks to be in very good shape.
