Well now ~ some almost seven and a half feet long, but the one on the left [which is curled] does the same. So I think that something 'liquid' goes into them for maturing [or what ever] the second one down seems to have a hook at the end, so it's hung ~ and they all seem to have a sort of segment bit, so that once completed, what ever it is can be taken out 'bit by bit'
That's it folks, no other idea
