Hey Utah from Alabama!
Yes it is the Koessler-Hammerschmid dealership. And they are english-friendly. (Would not make any sense otherwise, being a Morgan dealer, mmmh...)
They also organize Morgan holidays in Great Britain 4-5 times a year.
Including factory visits, Cornwall tours, etc. all in a rental Morgan, pretty cool.
They should be american-friendly as well, although you americans did that tea party thing...

Concerning your visit in may, I'm not sure I'll be around. Company has some tough times to beat, may be I have to work abroad a lot...
But nevertheless send me the dates of your visit, I'll do what I can for sure.
Greetings,
Alex.
