Hi Guys, I have got some great new info which clears up ongoing confusion regarding sigs on 1970s pieces

I have been speaking to an ex-Mdina worker who was there in the early 1970s concerning the signatures in the pics below, which I sent him via mms. He did not particularly recognise any of them apart the one that is dated 1973 that he thinks is Dobson, as 'his signature leaned to the right'.
Pieces were signed by Dobson if he was available, if not they were signed by Marie who was in charge of quality control and packing. He also states that (apart from friggers) no other members of the team signed pieces apart from the two mentioned. I think we can conclude from this that quite a few signatures were done by Marie and therefore totally random and not the signature of the actual maker or designer. This new info must put in to doubt pieces that are claimed to be signed by Said, he didn't sign pieces, certainly in the earlier days and these would have to be by Marie.
This is what I have suspected and explains the very random nature of the signatures we are finding on the bases.
