Very nice indeed! Not that I know much about buses!

The one with the black roof reminds me very much of the Midland Red (BMMO) motorway buses that existed when I was a youth!

Cheers!

I'm not well read on BMMO's buses but I think the black roof denoted a coach or dual-purpose vehicle, while buses were plain red.

The AEC 'Q' was quite an innvative vehicle with its side engine and London Transport took many of them to several different body designs, includng a small number of double deckers. BMMO were also innovators and designed and built several vehicle types of their own.

Thank you for the kind comment.
