Tele attachment Quarz 2m

Hi,
I am looking for TELE attachment for my Quarz 2m (should be 2.0x).
I can also buy it along with the wide 0.5x, which, however, already have.
Attention: http://www.ussrphoto.com/wiki/default.asp?WikiCatID=91&ParentID=2&ContentID=1291&Item= (esemple) is NOT compatible with 2M of Quarz version!

I think I have what you want.
I have a set of two accessory lenses for Quartz.
The tele is 2.0x.
Is there any other way to be certain they are the right ones?

Hello Kinoglaz
sorry but just checked the lenses and the tele is 1.9x
