Alton Vehicle HAA 701.

This picture was taken at Lord Mayor Trelore Hospital (LMTH) at Alton. The vehicle was, at the time, based at Alton and driven by the late Tom Parker.
The registration (HAA 701) was issued between Jan 1949 and June 1950. - I believe that most of the Welfarers that entered service during the 49 to 53 period, were out of service by about 1961-2.
Thanks to Ron Lilly for the information.
