Antique Cast Iron Fireplace Door Stop with Lion and Unicorn Coat of Arms

Interesting antique cast iron door stop.   This has been in my store room for years.    One of those things I purchased at an estate sale, then when I got it home I wasn't sure what to do with, so it disappeared into my storeroom.  That was 10 - 20 years ago.   Today I "rediscovered it", and decided to put it on ebay.

Cast Iron door stops are not my area.   From what I gather from a quick google search, this is not a common shape.

It is not marked with any makers marks, or other marks I can find.

About 12 1/2 inches tall, 12 1/2 inches wide and 4 1/2 inches deep.

About 15 pounds in weight.

Good condition as shown.
