Hi Sue,
I've just been over to the island and asked at the museum to see the original on microfilm they were unable to show me an original and showed me a transcript instead. They suggested writing to Malew Church so that's going to be my next step. LDS now have a copy ordering service which I use but this burial record on Family Search appears to be part of a collection which in the past they said was an index only of records which are held on the island not by the LDS.
