I would think that being early Mk4 (L2A3 type) single shot Police Carbine guns Sterling were using up the last of their Mk3 (L2A2 type) trigger mechanism assemblies. In fact, the FIRST Police Carbines were based on late Mk3 (L2A2) guns The later and 'naughty' Mk4 rock and roll trigger mechs are a direct fit. But you must promise to replace the full auto inner change lever with the existing neutered inner from your existing trigger mechs.
The same applies to the magazine catches buttons and adjustable foresights. I expect these are plentiful via the US and in parts kitsInformation
