Again sincere thanks folks for your supportive messages - and I'd like to take a moment here to say a very big thank you to Chris Stewart. :clap: :clap: His help is already acknowledged on the article itself, but I would like to say it again here.
In the early stages of figuring out this mystery I asked Chris for his help / thoughts. I was fascinated when he told me that all the 269s he had examined had 7 points on the prunts. Without his knowledge and observation regarding this crucial detail, the investigation may well have stopped in the early stages. So - thank you Chris, for your help, your knowledge, your expertise and your time. I am indebted to you.
I'd also like to publicly thank Lesley and Bob Smith (the owners of the comport) for all their wonderful help, their photos and for trusting me to undertake the investigation.
This really was an international team effort in every way. Without the help from GMB members who kindly checked their pieces, as well as photographing them (again thank you Tony H) we would not have been able to get the evidence checked so well.
Thank you again, everyone who has helped in every and any way.
