Introduction.
Welcome to my sales! 
First of all, I want to say.
 Practically all of the things sold me, not new ones.
 They are made of 20-50 or more years ago.
 I sell the same items in real working condition, that is, they have the service.
 I am thoroughly and meticulously pointing out the state of items, and the customer will have to decide whether to buy or not.
Sales on ebay makes very high demands on the quality of the goods, and old things must be as new to the concept of the buyer. 
Of course, I try and carefully preparing their things for sale. 
And yet, there are times when the camera or lens stop working. Judging by my reviews, it is fairly rare.
On Soviet factories was quite acceptable 4-5 percent defective products. 
I'm not talking about some things, such as Kiev-17, or Almaz-103 camera. In this case, the numbers are greater than 50 percent. 
You may be dissatisfied with your purchase, but in any case I put work and tried. Ask it to take into account before evaluation using feedback.
Therefore, when there is a problem in the first place please contact me.

                                                      About the condition.
I use the following scale state of things:
New - Like new - Mint(+,-) - Excellent(+, - ) - Good working - As is. 
A separate listing of technical condition. As a rule, I sell things in working order. 
At the lens state. Soviet lenses, even new, ones can have some cosmetic flaws. 
I put the original document Krasnogorsk optical plant. 
It regulates the amount of defects in NEW LENSES. 
As is clear from this document, glass state has never been perfect.

See the original document in the description photo. 
I usually point out even minor defects. 
This may deter a buyer, but I have to say that such defects have absolutely no effect on image quality.
But many Soviet lenses have excellent optical quality, are made of first-class kinds of glass and had a very affordable price.
