I found this at an old schoolhouse. 1900-1930 but then it was lived in as a residence to the mid 50s. I was thinking the guy that lived there must have owned one of those little monkeys that ride the dog around at the rodeo but did a little research and I come to find out it's an ashtray.
Yes, sorry, it's about 5" diam. I would have put a coin in there for size referrence but I didn't unearth any. Several good signals I didn't dig (got dark on me) so I'll be back.
