Cover of the Day / Unknown hospital ship

[Peter High]

This is my contribution to the 'Cover of the Day'. It is also a request for help.
The cover has been sent from an Army Hospital Ship. From the reverse can be seen the flag motif of B.I.S.N. Co. Ld, so it's a British India owned vessel...but which one?
The double ring oval cachet may at one time have had the ship's name at the bottom, each side of the star - possibly.
The sender's (?) name top left may also give us a clue - W. L. Allutt.

An attractive cover anyway - any suggestions appreciated.

Keep safe.

Sorry, Peter. If you don't know, how do you expect us to? Any query on hospital ships and we turn to you...

Hi Peter,

In my spare time.......... lots of that I search around a bit to try and come up with something. Rather than Allutt tried some options and found some references (old army lists) to Albutt, Miss W. L. 1620 - I know no more, this might got nowhere, but could this be a nurse or sister on the ship?

Google Albutt, Miss W. L. 1620
