Hello a day late!  I have some rocking chair movements that can be
used as a replacement, but are not identical.  They were made by Denis
Margot, in Switzerland at my request a couple of years ago.

However, I agree with Matthew: let's have a look at the original to see
if it is repairable.  I will be glad to do it for the cost of shipping
-- I love these little novelty items and try to keep them working if at
all possible.  Since I have several and can use mine as a comparison,
chances are, I can make the original work again.  Worth a try, anyway.

Send me a note and I'll give you an address if you want to send me the
movement.
