2 similar bikes, the one of the left is in London the bike above in Seattle
another mid range example set-up for touring. This one was also for sale in Washington State. Owner initially was asking an unrealistic $1500
Found this example on Ebay UK. Looks to be a premium build, Campy Components, drop outs. Nervex lugs? Unfortunately the pictures lack key details. 

New owner will have some sorting out to do. Notice the position of the shift levers.
