If you can take pictures and post them I might be able to ID the rifle.
If the safety is the same it's most likely a K98 bolt/action and was rebarrelled to 300 Savage and with a new stock.
After WWII K98 rifles flooded the market. Like I said Parker & Hale bought a bunch to use. They used the action but with their own bolts. Once the K98 actions ran out they started making their own.
They are easy to spot. If you notice on the rifle above there is a small cutout on the side of the receiver. This is there to help when using a stripper clip to load the rifle. These cutouts are only found on stripper clip fed rifles. Thus old military rifle receivers.
