Aha! The old Parker Hale sporting .303 conversion, very common and popular here in the '60's and '70's.
If you dont care to shoot it with a scope with the Monte Carlo style stocks, you can easily replace them - the Parker Hale rifles were given brand new commercial barrels and had good open sights; (although I dont think I have ever seen one with that .30-30 style rear sight with elevator, and a front blade they nearly all over here over flip over williams rear sight, and a bead front sight - maybe for the US market)
The five round magazines are worth a few dollars now too.

Additionally, I have never seen one where they took the charger bridge off, or had them drilled and tapped for a side mount - virtually every one I have seen still had the bridge, and were drilled on top of receiver for a special Parker Hale scope mount, which utilised the charger bridge at the rear. (A mount which takes PH scope rings - they were useless rings that always break, and vitually impossible to find now because of it)
