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.

My first thought was a centrifugal governor from a traction/steam engine but it could be a little small (no idea what size they were) but as it has a screw thread then no older than the late 18th century Wink

I showed a artefact to a FLO with a thread underneath but he wasn't interested in it and handed it back, it looked a real old item but as it was threaded he dated it 18th-19th century but looking at Archimedes Screws what the Romans used they obviously knew the benefits of a thread, so why couldn't threads be used on other items..... 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 Wink

Because the Archimedes screw (Greek) was only one thread inside a barrel to lift water not fixing and it wasn't possible to machine an internal thread until the industrial revolution Wink

P.S. I guess I should say that it would have been possible but just wasn't done until the powered age Wink

Cheers Geoff that explains that, the item I had was a internal thread  Wink

I watched a dig in London (on tv) years ago they actually found a Archimedes screw and lifted it from the ground in sections it must have been 30ft down, and surprising it was in good condition.
