I would be very surprised if Manx Museum supplied 10 - the time alone to find 10 films and wind to the correct place etc - also the wills of this time were often quite long - they will, I suspect, suggest you find a local researcher - also at 80p a page for microfilm copies you may find you have a substantial bill. As they are well beyond my period of interest (apart from possibly the 1841 will) I doubt if I will get round to summarising these
