Court Martial records

[Elliebob]

I haven't been on this forum for a long time but I know where to come for help.  I am hoping to access the record of a court martial held in April 1941.  I have the Gazette entry as the officer was cashiered.  (London Gazette 29 Apr 1941)

"Y. 6- L.R. Maj. G. C. Wilmot (11781) is cashiered by sentence of a Gen. Court-Martial. 11th Apr.1941"

I think it must have been pretty serious for this during war time.  He was my mil's first husband and served in the York and Lancaster Regt.
I am going to London at the end of April if I thought that the record was available at the National Archives or elsewhere would go to access it.  I can't see any reference to it online. 
Has anyone any idea how I can find out details please?
Thanks in anticipation, Ellen

Thanks Shaun, I have got the pdf of that and is what I quoted from (the copy and paste from the pdf wasn't accurate! I knew that he served in the York & Lancs with my fil. As they were both born in 1896 they are long dead so can't ask them!

The Kew research guide suggest that the details of courts martial so relatively recently may be still closed:

http://www.nationalarchives.gov.uk/help-with-your-research/research-guides/courts-martial-desertion-british-army-17th-20th-centuries/

As service records for that time are still not open to the public this may be the same.

Worth contacting them in advance?

Thanks.  I am not sure.  I thought I read somewhere that the records are closed for 75 years which would just take us to them being open.  I think I will have to wait a bit and do some more research/message Kew as I may not have time to get out to NA anyway.
Best wishes, Ellen
