Very cool lens, Jim.  Undoubtedly meant for large format but I am not sure of 
exact film size.   F16 rather a small  small aperture for MFT but at least it 
gets used!  Dr. Diffraction may not be pleased but current software tools can 
ameliorate the effect. 

8"  focal length--hmmm --about 200mm or 400mm FF equivalent on MFT.  Curiously 
back of envelope calculation  reveals that 
on 8X10 format would provide same diagonal angle of view at about a 28mm on 
full frame or 14mm on MFT so was really meant to be a WA!!

Wide to supertele in one lens, Mike
