Many thanks David. I hope we can find a physical bonnet emblem for him but if not I will certainly pass on your offer to him.
He suffers from Scheuermann disease, which means that his bones/joints in his spine are not grown regularly and he wears 4 braces every day (2 knee braces and a big and a small spine brace) and special shoes.
It does not matter if the emblem is a bit damaged so maybe there is a member out there who has an old one they are willing to dispose of.
