I have had a few of these in the past, but never one with the original linen bag as supplied by the vendor - that is quite a find. Because it has been in the bag for about 150 years, it is in extremely good condition.
They are very finely made - a few strands of semi-flexible steel form the central handle, and are held together with lumps of lead at both ends. The whole thing is then very finely and intricately bound in thin cord and painted black.
They were sold as defensive weapons, but - of course - criminals being criminals, were often used as offensive weapons. This is why eBay will not allow any sort of weapon to be sold on their site, whether or not it is a collectable antique.
So I have put it for sale on a site which actually specialises in selling collector's weapons, and I hope to make a few quid out of it. I just like interesting and historic items, whether or not they are weapons, or even self-protection devices.
I sort of don't blame eBay for banning things like this, though. There are plenty of young fools who would probably use it, given a chance.
