What next?

A bit of bus modelling today.  The model is a 1936 Leyland TD4 with a Roe body.  I'm modelling a version that went to Middlesborough Corporation and could have ended up with my fictional West Coast Motors fleet based in Port Appin.  None ever did but down at Machiranish, MacConnachies did have a couple of deckers from as far afield as Devon and London. I think an Ex M'bro double decker operated in Dunoon.  There's a precedent for (almost) anything.

However all the time I was fettling my bus (they can't touch you for it) my mind was on other things.  Any ideas where the next Port Appin building might originate from?
