Title: Any ideas please! Post by: SussexSeeker on October 03, 2015, 11:44:22 AM Hi found this about 8 inches deep in solid clay, not got a clue what it is.
Its made of brass has a screwed shank and has a lead insert, as you can see from a broken one I find too. Its quite heavy, ideas would be good thanks. Title: Re: Any ideas please! Post by: nobby on October 03, 2015, 12:48:18 PM gearstick off a roman chariot ::)

Its one iv been thinking about for awhile. Im not saying the above item is old though, and sorry SussexSeeker I haven't a clue what it is ;) Title: Re: Any ideas please!

P.S. I guess I should say that it would have been possible but just wasn't done until the powered age ;) Title: Re: Any ideas please!
