Take a look at this unusual "Made in Canada" wrench on ebay. Is this a T-1917 band wrench?

That is a confusing ebay sale. In the description it calls the wrench a Ford USA wrenche, but in the picture it is a Ford Canada wrench.
It also mentions a silver wrench that is in the photos that is actually not there. I think that the wrong photos were used in the sale and there might be some corrections to be made.

Rick, I think that spanner is part of the A model Ford kit. I do not think it is the T1917 band adjusting spanner.
Just my thoughts.
