Thank you for your reply, I don't have a picture of it yet, the bottom curved like a rocking chair leg , so it can rock from side to side if nudged.. kinda like a music penduelum.
Only one I remember was a scotch named 'Swing' back in the 70's,and if memory serves,it rocked front-to-back,not side-to-side.Don't know how long it was produced,I'm afraid.
Thanks, a friend of my sons found it in an old barn. He knew that I collected so he gave it to me. Lucky me huh... The next time that I take pics I send one in...
