Seems to have been a version control problem on my end. I wasn't running 
the code I thought I was.

Here's a short test case, and runs as expected.

#! /bin/sh

set -x
mkdir foo
touch foo/one-two
IFS=-
ls foo | while read one two
do
   FILE="foo/$one-$two"
   if [ \! -f "$FILE" ]
   then
       echo file "$FILE" not found
   else
       echo file "$FILE" found
   fi
done
