It has no teeth or bite marks on the moutpiece (filter) and it smells a little of tobacco but appears to have very little use. I would guess only once. The wood body is not scratched or soiled or chipped or showing any of the usual wear compared to the others I have examined over the years.
It measures 6" long.
Don't miss it, it really is the nicest example I have ever seen, it would be very hard to beat!
