Smiths Spencers but not so Happiway today

I usually try to do something interesting for Friday Thirteenth but this year it sort of sneaked up on me and I didn't have time to get organised, but maybe I might extent the theme slightly for a few days as I make some new scans. This is a breakdown I came across involving at Smiths Happiways Spencers coach in Chester, but the victim wasn't one of those AEC Reliance coaches I've grown a soft spot for as they had all gone by this time in the mid-Eighties and most probably another Volvo. From this view it looks as if the stylish breakdown conversion has an open back end but surely not as I'm sure it must have had to make some long cold journeys.
