Following a trip to the Wiltshire Rcord office in Chippenham, I can add a little more.
W.R.O. Ref; A1-125-60, 64
Walter Pinnock was held in Devizes New Prison pending trial on 8 April 1834 at Salisbury Sessions. He was convicted of the crime of 'Leaving his Family' and sentenced to 3 months.
On 3 July 1838 at the Warminster Sessions he was convicted, aged 46, of the Felony of stealing a hat and was sentenced to 3 calendar months hard labour at the Devizes House of Correction.
Seems to be a sufficiently unusual name to probably be the Walter we are intersted in.
Hope this helps. T
