Social services documents described his convictions as a "real cause for concern" and warned that children should not be left unsupervised with him.
In 1987, Harding moved to Gloucestershire where social services were aware nearly 20 years ago of his criminal convictions.
Gloucestershire County Council declined to comment on the fact that he continued to run a music box museum in Northleach, which was regularly visited by children, until his death aged 82 in June.
I've been to the Keith Harding museum. It's about mechanical music and I took the kids there. Think I saw him walking around behind one of the counters.
If I offer to help my wife out with bringing stuff out from a Brownie hut, she tells me I can't because I'm not cleared. But a convicted child sex offender running a museum for 20 years with loads of kids in it? No problem.
It couldn't possibly be that CRB checks are a load of security theatre, could it?
