The first time I ever saw or heard of an L42 in private hands was in about 1979 or 80 when a dealer in Wiltshire had about 4 or 5 of them plus a couple of L8's, bought at a Government auction/sale when a large Ordnance Depot in Berkshire closed down. These rifles were missing the front or rear or both pads and came as pretty well bog standard rifles.
At the time, I wondered whether these rifles were or might have been the donors for the .22" No8 rifles that had been fitted with body pads. But anyway, that's the first time I ever saw one in private hands
