I have owned now 2 DCRA No4's (I live and collect in Australia). The first was many moons ago, was reputedly swapped at a Palma match between the Canuck and Aussie shooters (Aussie giving his Omark, Canuck the DCRA No4). Can't confirm any of it, as the prior owner has passed on. It had a Sterling magazine, was a Long Branch action and had the small aperture LB standard WW2 "Singer" sight. Hardwood bedded and also cork bedded.
Second one I acquired yesterday (for too much $, but what the hay...). A little more interesting in that it is a No4 Mk 2 (1952 PF serial range Fazakerley), that seems to have first been Parker Hale accurised (or maybe even started life as a T4 with PH?). Has the full stylised Maple Leaf on the right receiver ring. Conversion number is 1283 and is on the right receiver ring, bolt handle top and barrel. .
Full blonde beech No4 Mk2 stocking up, with resin reinforcement at the draws and other critical areas. Enfield 7.62 (CR141A 65) magazine, clip guide and extractor. Hollowed bolt ball. LB milled rear band, upper band and foresight protector. Wasted triggerguard (as with the No5 and some late No4's). Original Brit "B" (CR670) marked sight (probably replaced). Probably going to put a PH4 or 5C on it in time. Buttplate brass, with "579" stamped in large font on the trapdoor. Front sight blade has white paint on shooter side. Barrel has typical CA 7.62 marking.
Interestingly, presumably at time of conversion, the Suncorite paint was removed and reblued entirely (except magazine) ala Long Branch/CA Dulite blue, which makes it very pretty. A quasi LB
Haven't shot it yet, but I have 100 rounds of MF82 and 86 (or as we call it, Made By Fred

) milsurp to play with.
