The 12 footer arrived and although it looks superficially dreadful with badly done varnish and bent and rusty guides, it is at least sound (though with a slight droop in the tip).
I already have the replacement guides, and enough of the same thread as I'm using on the 14 ft version to complete the rebuild.
