You are looking at an old, 8" Adjustable Spanner or Wrench marked "  Bahco, 8", 0671, Made in Sweden ". This is used with some light wear and surface corrosion marks.

One of several old tools I am currently selling on ebay.

Please note, all items posted outside of the UK must now be sent via the global shipping program by order of ebay. I no longer have control over the amount charged or the service provided.
