Parker Hale rifles were common in Australia & New Zealand in the 1970s & 80s . Some of them had deluxe stocks that had a Monte Carlo comb & skip checkering with white spacer in the but & pistol grip.

The simple method of refinishing the stock is to (after removing all the metal parts & recoil pad) use some paint stripper & remove the varnish. Use a toothbrush on the checkering & very fine steel wool or 120 grit sandpaper on the stock. I have even wet the stock & used a clothes iron with steamer to lift up the wood fibre from the small dings. The big gouges cannot be raised & could be filled. I am careful with the edges of the barrel channel & other inletted parts which I prefer to leave as sharp as possible.

Sealing & finishing with Tru-oil is quite simple. There is another post on this site where DarylS has give some good advise on stock finishing.
