These are really big heavy industrial blocks as used in forestry. Wooden bodies are around 400mm long.I obtained them for decorative purposes but they're still hanging in my garage. They are big and heavy so I would prefer buyer to pick up, but freighting is a possibility. There are single blocks, snatch blocks, and double blocks, 8 in all as per photos. Auction is for two singles only - if you want more (or all of them) let me know and i will set up a new auction.
