I hesitate to ask because I'm sure the answer will be simple, but this is driving me slightly nuts.

I've been digging a massively trashy block in Geelong, Victoria, which I think used to have a farmhouse (or at least a shed or outbuilding of some sort) on it. The building was demolished sometime after 1947, and the block has been vacant for at least 30 years. I've found quite a lot of automotive stuff on it, which suggests that it might have been used for storing and/or working on cars, some of which date to the 1970s. I've managed to find some horseshoes and an 1890s padlock to suggest that artifacts from the prior occupation still exist, but no coins yet.

Anyway, all over this quite large block, I've been pulling up these things. They're like half-sawn pieces of galvanised pipe. Many but not all have flanged edges on them. Many but not all have either holes where they appear to have been nailed or screwed to something, or weld beads to suggest that they've been welded to something. I've pictured five of them, but I must have dug up close to 30. Also found a metal tag with "S/WELD" stamped on it today, which may or may not be related.

Welcome any and all theories about what these things might have been for. Could just be scrap that was dumped there, but they're well spread around the site.

With the days getting shorter here, I only have an hour of light left after work. I had a couple of quick hunts at a town on the way home which used to be a reasonably busy railway hub, now pretty quiet, so I thought it was a good chance of a decent trash:treasure ratio. At a grassed area outside the railway station, I picked up my second-ever florin within about ten minutes, then nothing for the rest of the time. Next day, same town, this time grassed area opposite old pub. Found a centenary medal within about ten minutes, then nothing for the rest of the time. Two days later, overgrown area next to old water-driven paper mill, found my first ever sixpence within about ten minutes, then nothing the rest of the time. Either I'm really good at finding the one single find that exists within a certain area, or really good a missing all the others.
