Don't worry me what bus you have, so welcome! And K+ for having the balls to admit your a prototype owner!
'68 are a great bus although parts can be a nightmare :- trying get a photo off of flickr but thats also playing up ??? I was parked next to a late bay the other day, tried sparking up a conversation the way you do...they were Norwegian I think so I settled for smile and a wave ;D I've got a photo pf them parked together I'll have a look
