Just back from collecting the machine - weather wasn't very kind but we stopped at Tintern Abbey for a coffee, and visited the very good second hand bookshop there too.
Machine does indeed have lots of bits - photos hopefully attached - and was used by the sellers father to make reproduction antique police uniforms as part of his display of antique police memorabilia!
We most like won't be keeping this, just make it lovely and then sell it along - no great profit required just the joy of making it work again
