Fed 100mm lens trade only!

I looking to trade 100mm Fed lens like this:
http://www.ussrphoto.com/Wiki/default.asp?WikiCatID=87&ParentID=2&ContentID=317&Item=FED+100+mm+f%3A6%2E3

on any other Fed lens, except standard 50mm lenses of cause
or Tair-3 (not Tair-3FS) lens,
or Jupiter-6 lens.
My lens is in very good conditions. Included back cup.
I also throwing in 85mm viewfinder to compliment this lens. 85mm viewfinder is not exactly made for this lens, but it close enough to use it with acceptable results with 100mm lenses.
