Your Z - Mike Coogan - Z1, Z1B and Rickman CR
These Zs belong to Mike Coogan.
Mike keeps them in his dining room!
Another of Mike's Z1Bs, a Candy Super Red model with the twin disc option, features on the Z1B page of this website.
...and here is another picture of two of Mike's Zs; a '73 Z1 and a '74 Rickman CR.
