Yes indeed the same horse hot stamp as the LazyS mold. Mike Auterson let me shoot this photo of the chip case that a bunch of Mecca chips were in. The horses were there too. He let me have one. I can't tell from my photo what mold the horses are They almost look like Hub molds but, he gave me the S mold. At that time I didn't give the mold much thought. I hope I didn't flush my original file. I had to dumb down the file size to post it on the BB back then.
What Gene said about the bigger shovel...I don't have that hub either.
