Very Unusal Vintage Potato Masher

This is a most unusal potato masher, I couldn't find anything remotely like it in any of my kitchen utensil reference books. It has a unique offset handle. I believe this to be from the early 1900's or maybe earlier. It is in very good condition with only a minor amount of surface rust on the wire. It measues 3 1/4" x 9". Shipping will be 5.50 within the USA, all others please email for amount.
