Hello all, I am not a "horsey" person myself but thought that someone here might be able to solve a mystery which is puzzling me. My wife and I bought an old farmhouse here in Poland back in October. We are starting to clear out the clutter from the barns, there is A LOT of clutter! Amongst the curiosities are some boxes of assorted metalwork which includes ancient hinges, nails and horseshoes which may date back a century or more. We suspect that there have not been any working, or any other type of horse, on the property since well before the second world war. I attach a photograph of some of the horseshoes that I am trying to clean up as we may use them decoratively in the future but I was curious about the projections on them. I assume they were there to provide traction in the winter snows but if anyone knows for certain I would be fascinated to know.
