Re: Help to ID this lens.
First, measure the focal length and aperture to see if it's really an f/5.6 wide open. Could be a Frankenstein lens as you suggested, or damaged, or in the wrong shutter upsetting the spacing.

Rough measurements (didn't have a ruler with me at the time) put the max aperture between f/11-f/16. With no lens brand on the front elements, again makes me think "two rear elements from two wide angle lenses"
Re: Help to ID this lens.
The shutter is from a Fujinon NW 150mm 5.6, and the rear cell looks like it might be the rear half of it, the serial number is correct for that anyway. The front lens looks just like the rear cell of the Fujinon SWD 90mm 5.6 that I used to own. The diameter of the 90mm cell should be either 80mm or 77mm if I remember correctly for the NSWD version.

Your post got me to gig up and take out my FUJI catalogue. Based on filter sizes and shapes: Larger set of elements probably the front elements of a 90 NSWS and smaller rear set of elements probably off a 125 or 135mm NW. Max f/stop measures in at about f/16. Based on GG image, this mongrel lens probably isn't worth shooting some test 8x10 negatives with.
thanks...

Could also be a plasmat with one positive element missing. You'd have to disassemble it to see. The shutter alone is probably worth more than the shutter with the lens.

Agree... I shot an 8x10 negative earlier today with the lens wide open. Was very difficult to even determine focus. On a Bokeh scale of 1 to 10, I would rate the mongrel lens as a 0.0. Will be putting the shutter up FS.
thanks everyone.
Re: Help to ID this lens.
And somewhere out there are the front groups of those two mysteries...

I think you are right -- and if they are Fujinon, they are not marked. Only the front elements were. And the black shutter means it's fairly recent.
You can figure it out -- assuming they are Fujinon by looking at the shutter and the front and rear diameters of what you have.

The Fujinon NSW (they never made a NSWD) 90mm has a 67mm filter thread, but the 105mm is 77mm, for example.
Whether you can use "them", as is?????????????

Depending on what lenses they actually came from, the front and rear might be quite valuable to some shutterbugs out there.
If you tell us the front and rear diameters of the two groups, we can probably help you figure it out.
