This is the variant of the W402 with the large open end on the right when reading the part number. An easy way to tell the difference is that the end hole on this version is partially taken up by the cutout square, on the other version the whole circle is there. This is a large wrench, 17" long.

I now have Ebay set up to add $1 per additional item for shipping. This will somewhat make it easier to combine shipping as a buyer. You won't need a corrected invoice. If you are going to buy quite a few, say like 10, I should be able to refund some of the shipping cost back to you now. But it will depend on size of box and weight too.
