I knew you had one after searching out info about 1956 Faz's on the web and seeing your postings, I did see another posting from somebody in my extensive shearching who said that basically as these were the last limited run and they had already settled on and were preparing to start making the L1A1's they all but a few went straight into long term storage and kept to the last when they were then later mostly destroyed. It seems that only about 10,000 in total were made as the production run only lasted a few months before the order to finish up send the factory to Pakistan.
It must be lucky that at least two ended up in Canada. When I got it I didn't even realise that it was from the last run of Faz No.4 Mk2's, I was just looking for a nice No.4 Mk2 to add to my LE collection, I was really surprised when I started to search out the serial number to try and determine who or where it may have been issued too.
The serial number on mine is 402**, I would post some pictures but I have just taken it down to give it a good cleaning, linseed oil the wood and check to confirm it was all matching, which it is right down to the magazine.
