Hi Nick:

Patent Photo-Electric Keying Head, F. Kunc (Boehme Inc), Dec 12, 1933
has an optical assembly that needes to be able to read the holes in the paper 
tape when the separation between holes is much smaller than a hole radius. 
This may be the missing part on the RD-110/U ?  See drawing at:

There's a larger drawing in the patent on page 3.


Have Fun,
