When we had access to the registry data I noted that there were many L2A4's registered in Canada...I still have hope that some of them ARE L2A4's rather than the typically ineptly miss-described items usually found, such as yours seem to be.
There certainly should /could be real L2A4's in Canada...the original tool room guns and the manufacturer test samples assembled at CAL with CAL, Enfield, Faz & Sterling componants.
Could there be some at CARDE?
