another document that I need help with please

[Morsey]

After all the help that I received concerning my Grandfather Albert Henry Sharr over the last few days I have found another that I need help with.

He enlist into the 22nd (Queens) London Regiment 16/08/1916. at some time he appears to have joined the 2/6th Regiment Royal Welsh Fusiliers according to the info that i found today. Does anyone have any info to explain his transfer to the RWF. Was he still in it when he was sent to France to join the Cheshire and consequently the KSLI?

Does anyone have any information explaining the document below please?
