Very pretty Mr B. I remember the sensation caused by that style of bonded construction, when they first appeared in this country, ridden by the Polish national squad at the 1973 (or was it '74 ?) Milk Race. They were badged as WAJAC, constructed by a Polish frame builder ( Walter Jacobowski ) living in Italy. I assume that Alan must have bought-out WAJAC? At the end of the final stage on Blackpool prom the entire team propped their bikes against the promenade railings - talk about bike-geek magnets.
On a different tack, with your dodgey knees you should surely consider lowering the gears for exploits around the Dales?
And don't park it up with the gear levers in the position shown. Change gear so that both the levers are fully forward; that way you won't stretch the cables unnecessarily - it all helps to keep gear changes crisp.
