I'm reading Barnacle-Bill's post as "I bought a part-built second-hand kit and still expected the manufacturer to address my problems with it".
No, I never purchased a part built Kit, I purchased a brand new still in the box and the box still in the cellophane 1/48 Scale Model Buccaneer
Then I am confused. You refer in two separate posts as to the kit quite clearly having been started:
As the Kit was purchased, even from a dealer, with the Kit half built,
I purchased the Kit on ebay, no return, especially as the Kit is part built,
In any event, and however poor the kit is, I don't see through how all of your legal quotes any company can be held responsible for an aged kit. Putting aside your twice-made assertion that the kit was already started, the contents was what the box described, right? A 1/48 Buccaneer that the purchaser had to assemble, needing paint, glue and skills?
Airfix have indeed addressed problems with the new Sea Fury but supplying new fuselage halves, as they would be duty bound to. I am afraid to say, how they have any responsibilty for a decades old kit that was of its time and not that great to start with is anyone's guess.
