#3 Bell has not casting marks or other identifiable (to me) markings. Sounds great. The yoke attaches it to a post I presume. The bell is 17"across the bottom and approx 20" high.
I have a two tier mahogany table with 4 legs. It has two labels under top tier, Genuine mahogany tag, and Imperial Grand Rapids Mi plus a I believe it shows the number 4151 in black.
