Hi All
Subject to my previous post I have sort of solved the identity of the swiss army knife. As mentioned by a member the knife is a pre 1974 and has a London gold hallmark for 1973 to both sides of the shell done on the inside. I think the London maker is 'R&R' although it is difficult to read clearly. I have included some images of the knife and the hallmark. I cannot find another example, is it possibly a one off commission?. There are no import marks so issue it was produced here in the United Kingdom.
Any advice would be appreciated.
Martin
