Somebody has probably seen this
http://discovery.nationalarchives.gov.uk/details/r/C9520813but has not seen the document which it refers to, which I think is the document attached.
The document is WO 121 Royal Hospital, Chelsea Discharge Documents of Pensioners and it's for a discharge in 1821.
WO = War Office, which was the holder of the record prior to it's being deposited in the archives of the UK National Archives at Kew in London.
If so, then it looks as though there might have been a transcription error with the regiment number, and the regiment referred to on the document index as the 51st should really have been the 57th.
