What is 090 contra?

[teddy]

I own 2-090's and a 090g. but what is a 090 CONTRA???????? (Or what does Contra refer to?)
Thanks guys!

The reason I ask, I found some one in Germany to sell me parts, but a lot of the parts have Contra attached to them in the description.

Most saws sold under the name of "Contra" were in fact 106 cc .One model of Contra and one or maybe two of "Lightning" were 137 cc or the same as an 090 .

These are very rare saws .Perhaps that is what is to be taken as an 090 Contra .

The Contra,Lightning  and the 070 are basically the same saws they way I understand it or close to being the same .In fact the 090G is an 070 with a gear reduction unit .

So what I have seen with my saws(090 and 090g), is that they are the same except one with a gear drive.
And there are other forms(070, lightning, contra) are more just a difference with cc's?
Thanks AL_SMITH!!!!!!!!
