On the same day as my visit to Auto-Spares in Bingley I went to see these mobile polling booths with Shipley Urban District Council and was thus able to see, quite remarkably, no less than five of Oldham's Crossley single-deckers in one day.
The three here had all come via Auto-Spares and as far as I am now able to verify were 363 (nearest camera), 364 to its left and 300 in the background.
