[QuadList] blueprints for the 1938 RCA Empire State TV antenna discovered...

Ok  so this  seems  to  be  what mine is all about.

By 1938, NBC had again remodeled its  antenna on the building. The 
experimental station, then designated W2XBS,  broadcast a picture with 441 scanning 
lines. Transmission was within the range  of 45 to 50 MHz. with various 
picture-to-sound carrier spacings. A new NBC antenna was installed by February 
of 1939  (Fig, 2), and in January 1940 the company began regular FM operation 
from an  antenna at the same site. (This station was W2XDG. operating on 
42.6 MHz.) 

now, I would assume  that  with  drawing dates  of  1938    the  1939 
install date  is the   same  antenna.

Blueprints  for the 1938 RCA Empire State TV antenna discovered at  SMECC
Is it unusual to have these?

They were in a file box   with the Brookhaven  Cyclotron   Blueprints.

they have been probably folded up since '38   I need to  'relax' the paper 
but in the meantime have been transferred to the  banks vault in  case  
this is the only set 
around.

This  would be the   antenna  used  for   39  worlds  fair   historic   
rollout   eh?
