Cuckoo clock - working (Heeley S2)

This was given to us 6 or 7 years ago via a lovely freegler in pieces (the clock, not the freegler), a clever friend of mine has fixed it, replaced some of the bits and it does work. It no longer fits our house. It comes with the detailed instructions from my pal and the bird doesn't "cuckoo" as much as rattles and doings the hours but it does pop out its door! It is missing some of it's ornate fittings but that's doesn't affect its use.
