From what I can tell, there were at least 2 different rings and clamp systems for the clover shaped signs. One used a 1 1/4 inch pipe and the other used a 1 inch pipe.
The large round, embossed bases, have a 1 inch pipe thread, while the smaller clover shaped bases have a 1 1/4 inch pipe thread.
I do not know the pipe size on the first base you have pictured. I have 3 different clover shaped signs here, and they all use the ring and clamp that calls for a 1 1/4 pipe.
I also have an unused ring and clamp that would use a 1 inch pipe, but I don't know what sign went in it? It is also clover shaped but the signs pictured below won't fit in the ring correctly. The ring seems to be bigger than the sign. Both signs pictured use the 1 1/4 inch pipe and clover shaped base. The green colored sign is mounted on the wrong base with the use of a reducer adapter!
Do all of them that look like this use the same mounting hardware?? I couldn't begin to tell you. LOL
