Hi Noel
            Your ps comments are very perceptive.
I have no doubt that people out there are gathering TTL  even as we speak.

The one I always call to mind is the guys who built themselves flight 
  out of genuine parts.

I've seen replica cars of all kinds.
Boats yes
Steam Engines are good but one group built a brand new railway engine 
from 1930's drawings.

I think its got to the stage where if we can cooperate the result will 
be more than the sum of the parts.
There is already a spirit of mutual assistance amongst the list members.
Working towards a common goal transcends any other personal aversions 
people may have.

As you know I'm collecting front panel designs and recreating the 
original artwork.
Apart from a few mechanical details in print sets I have not seen any 
detail panel drawings anywhere.
Photos yes also line drawings in handbooks. All too small to be of much use.

Oh well I'm getting there but it can be slow. (interesting all the same)
