you can borrow the film via any Mormon FHC - the film is identical to that at the Manx Museum who also keep the will originals - you may be able to get the Manx Museum to provide a copy - at one time they did not have the staff but recently they have provided single requests (multiple ones get back the suggestion to employ a local researcher) - enquiries@mnh.gov.im
However the copy from microfilm is not always that good and at the Museum costs 80p/page.
