I am planning to visit London next week to do research on a museum
quality English Organ Clock.  My research is to find information on
Isaac Rogers, musical clock maker around 1750-90.  This musical organ
clock plays 8 tunes on a wooden barrel with 30 pipes every 3 hours.
It is in a tortoise shell and dore' [gilded] bronze case.

Could anybody please refer me to fellow collectors of quality clocks
or mechanical music collectors that I may contact while I am in London.
Thanks in advance.
