Thank you my liege! I shall carry it with honour until usurped. When you say that these are the only 2 known of this configuration, what are the defining characteristics?
It looks lovely Richard. Very very nice. Definitely late Heidelberg production and looks like the same specs as mine. Funny thing, your "air sock" under the bonnet is green-blue to suit your upholstery (?) while mine is red which matches my upholstery! I wonder if they really did that or is it just coincidence.
Your engine number 193018760 is "later" (higher) than mine, which is 193018733. I pass you the baton of "last produced Heidelberg ID" (surviving).
Thanks for posting photos,
Leconte
