The pic looks like a No1 Mk1 (with mag cutoff) converted to Mk111 spec by adding the charger guide etc.
The cocking piece on the rear of the firing pin seems to have come off a No4 rifle.
The Parker Hale rear sight was a popular addition, mostly used for target shooting.
The rifle has been modified several times, some of the mods possibly done privately. Sporterizing the rifle might have made it a decent hunter, but destroyed all originality it had left.
Look for a 2-digit date stamp on the flat portion on the barrel, right above the chamber. This may indicate the date a new barrel was fitted.
