This is a heavy cast iron shoe stretcher.  I have not attempted to clean up the dirt or rust as I am not an expert and might do more damage than good.  See pictures.  It is large and heavy.

I believe it dates back to the 1800's form research, but cannot be sure

This antique cast iron shoe stretcher is a unique piece for any collector or enthusiast of mercantile antiques. The adjustable design allows for a versatile display, and the sturdy construction is a testament to the quality craftsmanship of its maker. This item is sure to be a conversation starter and a prized addition to any collection.
