The National Archives has answered my question - response from them below:
Descriptions of the Scutari Depot Muster books and pay lists can be found in discovery. These records have not be indexed any further than they appear in the catalogue, they are not searchable by name.
None of the records in WO 14 are available in either digital or microfilm format. The documents are available in their original format. To view them you can visit us (please check our website for opening hours, closure dates and details of the two valid forms of ID you must bring to look at original documents), or as you live in Australia you may wish to consider a paid search.
Would love a trip to TNA ....... but ......
