Hi BC,
Though David Kirkham mentioned they are currently busy with pricing, you can try Hawk Cars in the UK:

Or Phillips Classic Cars in Germany ... speak to Fritz:
philipps@scm.de
Either way, both are European Kirkham dealers and you can avoid the pricey import costs from the US.
As Skippy mentioned, AutoEsHuis in Hardenburg Holland for Superformance ... not to far from you (als je het niet erg vindt om daar naar to te rijden)
There is also Gardner Douglas in the UK:

Several other options in Europe are available as will ... the following Website lists Worldwide Cobra Manufacturers:

Hope this is helpful ... good luck en groetjes van Nederland
