For your consideration, here is an Old EKCO Forge Potato Smasher, Stainless Steel, made in the USA.  It measures 9 3/8 inches long and has a diameter of 3 inches.  It has a little wear on it.  This is a nice heavy duty kitchen tool that was built to last.   

It will be mailed in a box for protection.  Item pictured is the actual item for up for sale and comes from a non-smoking household.  (647.11a20a-.13kx1)
