Thanks for the further information (much of which you also gave me in the other thread).
I was under the impression the frame (not the components, which are, I agree, junk) was in original condition aside from being a bit decrepit; so if that was not the case, then that changes things. So I agree, once a frame has been modified, or damaged to the point that major surgery is required, then whatever value that accrues from "originality" has already been lost. The frame becomes a blank canvas, from which you can create what you think it was originally, or whatever you want.
Thanks for indulging me this (totally unnecessary) debate! I will now look on your project a bit more cheerfully
