For sale in the USA, was this an old capital city bus? ...
It's actually H144GGS. Bus Lists on the web show its first owner as BTS at Borehamwood. I can't recall whether these ended up with Capital / First London subsequently. Capital Citybus certainly operated very similar vehicles - we had them on the 212 when I was a regular user of that route.
Ah - a google search brings Ian's Bus Stop vehicle histories. Remained within the Blazefield empire for its whole life - ended up with Keighley and District. Looks like the yellow livery was applied when it was downgraded to schools work.
Ah, yes, BTS, on the 114 ...I recall the Dennis dominators on the cc routes in particular the 97.. fleet numbers 267,68,69,70 etc... I think it was fleet number 132 for the 212 ... I recall the J148 YRM on the olympians ... I used to live in walthamstow prior to Australia ... and thanks for the correction of reg plate.
