Disability transfer/ Meaning of Abbreviation

[Neil_A]

Hi

I've found some further records regarding the movements of my great grandfather during WW1.
During his period of service he was moved from one regiment to another, from what I've read not that unusual. But the transfer involved a movement from France back to Home. The transfer document also references a disability.

Has anyone seen this code before or can help translate it?

He was also described as a B1 - which means he was fit to walk and shoot, so the disability referenced is a bit of a mystery. Unless it was the WW1 equivalent of Not Applicable!!

Many thanks

Neil
