Charles,
I also have a liking for these and have quite a few.
Rumour has it that everything is bigger in the States but perhaps this time we win !!!!!
However, This is the largest that I have seen. No scabbard unfortunately. Please forgive the poor photograph, I know it is unusual in England but the big yellow thing in the sky is out at the moment making it hard to get decent photos.
Cheers
Royston
