Hi all. I know it has been a while since my last post. I will post again real soon. Lots of great finds in the past month! One thing I found today, which is very interesting! I found this, what looks like to be some sort of bottle stopper. It also has what looks like a coin slot. It is at least 75 years old or older! It is cast iron or heavy steel, It has engraved H and R manufacturing. Anyone that has an inkling of what this might have been used for...I would surely like to know! Thanks for any help!
