Interpreting record

[pjaj]

I have a pdf copy of the navy record of a relative who served from 1881 to 1919. He first retired in 1909, joined the RFR Portsmouth and rejoined in 1914. Most of it is legible and some bits will need access to the original.

However I would like help on one or two things.

From 1.1.1915 to 25.2.1917 he served on what appears to be

M Fa Barca (Lock Royal)

M = ?
I guess Fa = fleet auxilliary
The letter "B" could be a "J" or and "S" or maybe something else, in any case I can find no reference to any of the possibilities or to Lock Royal.

I've just found this very useful post

This explains a lot , but what were the good conduct badge designations G1, D1 and R1?

There was one not covered in the "Remarks" column "£3.10 GC&B Lady '94"
C.G & B = Clothing and Bedding Gratuity, but what about the "Lady '94"
Later on there was a similar "£11 GB Lady <illegible, probably a date>"
GB = Bedding Gratuity.

Any help would be appreciated.
