Neil and Chris, you have missed the point by so much that I'm not even going to attempt re-explaining, or stoop to petty insults. You have your ideas, I'll stick with mine.
My apologies to all those who also misunderstood what I wrote before - it looks clear enough to me, but obviously isn't.
Catbed,
I think there is a stir going on here and I agree with you.
No misunderstnding here, misunderstanding is in the 'evil'
eye of the reader. The topic now seems to be, how much am I worth (Labour put into model) answer, sadly Nil. Even if your are a brain surgeon or rocket scientist, still nil. Unless, someone is prepare to buy the model with your value of your labour.
All the mumbo jumbo about plumbers etc is all irrelevant.
A plumber is selling a service that is used/needed by
very many. Whereas a model boat, plus your time, (value nil) is used/needed by how many ...........well work it out. You won't like it, nor do you have to, but the reality is the Plumber wins hands down.
As someone else put it simply, supply and demand, offer and acceptance, too dear offer refused, supply and demand.
