Thanks for all the replies, they are appreciated and have been passed on to Ken (who is not on the internet but will hopefully get to see this)
Just to add a little more information and feedback from Ken:
....the yellow one was a skip find.
....the Quinn looks like being a "Harry" although it apparently makes a difference to the restoration as to which "Harry" it was, this one does not have a Q after the frame number which implies Harry Quinn jnr.
....the Fothergill had bent forks (now aligned) and has been professionally painted.
....the Soens was a skip find and has been re-sprayed.
....the Whitcomb was a skip find (frame only in very good condition, no forks)
....the Tierney has been re-sprayed.
....the Sirius was a skip find and has been re-sprayed.
....the Claud Butler Saxon was a skip find in very poor condition (frame and forks) and has been professionally painted.
