Out of interest, there was a minor error put out about the L4A3 and 5 guns. The A3 had 2x barrels while the A5 had one fully chrome lined barrel.
Not all of the converted Mk2/L4A3 and 5 guns had a folding cocking handle either. Those that were converted from Mk2/1's had them of course and so did (?) those converted for the UKMilitary. BUT it's not as simple as that because some converted for the UK MoD clearly didn't have folders. Some Navy ones were non-folders, based on unmodified Mk2 guns. Accordingly, the parts lists were emended later to show the non folding cocking handle annotated with the 'either/or' mark!
The person who took this matter up with the Ordnance bods came back that during the late 60's/early 70's, some Commonwealth nations couldn't afford the full works so they just had the basic 7.62mm conversion done. Their clapped out heaps of tat went into Ordnance and they got virtually brand new FTR guns back. Eventually their heaps of tat went through the system and the Navy got them ......... It's a long convoluted story but interesting none the less
