I believe the tape Mr.Tennyson referred to was put over the curved end 
of the roof monitor on ALL 1700s, not just the interurbans.       Look 
at photos of newly delivered equipment  --  definite gap between monitor 
and roof at the rounded front end of the monitor.       These URLs 
clearly show the cars as delivered WithOut Tape::

Tape was later placed over this end and remained until The End!       
Never saw tape over the side screening  --  nothing for tape to stick to 
here  --  tape wouldn't stay on screen very long.       The following 
show the tape over the end:::::::

http://206.103.49.193/pitts/htm/pitt127.htm  --  tape pulled loose here!!


Coverings of metal  *may*  have been placed over the screening but don't 
know if it was the 17s, 1600, or 1630  --  Probably None Of These.       
Seems I saw a reference to such but not a clear memory.

The small air scoops fore and aft on the 16s and 15s were regularly 
covered in winter In The East End but Not in the South Hills  --  donut 
know why that is!       Don't know about North  --  didn't go over there 
much.
