LOL. No need to take it apart. This box was on my shelf, I forgot I had it. Sorry, it is a bit worn.
Cheers,

Huh. If you take off the front element what's left is similar to the unusual scheme used in the Fujinon 2.2/55. Interesting. |

Such a sheme does not make sense, if You haven't the refraction indicees of glass and radii of the lenses.

I have all the original paperwork for the lens. It includes the same diagram and lens specs such as length, angle of acceptance (75 degrees), MFD (.23') but doesn't include radii of the lenses or refractory index.  Maybe someone can take their's apart and measure such things.
