Just so happens there's this guy called Castro ;^> who keeps copies of 
most setups and packages ever released in the Cygwin Time Machine:

http://www.crouchingtigerhiddenfruitbat.org/Cygwin/timemachine.html

and circa (TM) 6 years ago there's copies of tcl 8.5.18-1:

http://ctm.crouchingtigerhiddenfruitbat.org/pub/cygwin/circa/64bit/2015/09/14/161026/index.html

with the tar at:

http://ctm.crouchingtigerhiddenfruitbat.org/pub/cygwin/circa/64bit/2015/09/14/161026/x86_64/release/tcl/tcl-8.5.18-1.tar.xz

$ curl -I 
http://ctm.crouchingtigerhiddenfruitbat.org/pub/cygwin/circa/64bit/2015/09/14/161026/x86_64/release/tcl/tcl-8.5.18-1.tar.xz

so you could run Cygwin Setup to install tcl3270 and its dependencies 
from that mirror URL with options:

-X, --no-verify		Don't verify setup.ini signatures
     --no-version-check	Suppress checking if a newer version of setup is 
available
-O, --only-site		Do not download mirror list, only use sites specified 
with -s
-s, --site URL		Download site URL
