Just been in touch they may have some undersized shells depending on the OD of the journal. Cheers Rick.

They were very helpful, but unfotunately no joy on the shells. If i was desperate he could try and order some and they then regrind the crank in the worn area and then regrind the shells to suit allowing for clearences etc. Quote about £100 which what some dopey git on flea bay expected me to pay for a crank alone!!! he recieved a polite email!!

Wouldn't it be cheaper option to obtain a good used crank (preferably off a reputable member in the classifieds here!) and use some new standard bearings?
