Hi Folks!
Thanks for all the great feedback.
I've been doing some digging and had a great time talking to the curator at Leeds Armouries who told me about a book called "Those Entrusted With Arms"which goes into some detail about the old Lignum Vitae truncheons.
I ended up buying a copy from Amazon for around $12.
I also visited Leeds Armouries and took a few photos while i was there
I slapped them on my Flickr page if anyone's interested

I used a Cold Steel Sharkie pen as a size guide as i always have one in my pocket. It's about the size of a bog standard permanent marker.
I wish i could've taken photos of everything at the armouries, it's an amazing place (especially the Hall of Steel).
I plan to go back there soon researching Duelling pistols and swords as well as Filipino weapons (another pet project or two

)
If anyone in the UK sees any truncheons up for auction please give me a heads up...i'm totally fscinated now...
Thanks again
Great community
all the best and happy new year
Andy
