READ THE TEXT BELOW BEFORE YOU LOOK AT THE PICTURE; IT WILL NOT BE FUN OTHERWISE --------
A woman came to a service station and asked for a 710. Not understanding what she wanted, they asked what it would be. The woman said that it was a thing that used to be in the middle of the engine and that it was now missing, so she needed a new. She did not know what function it had, but the 710 had always been there. She was given pen and paper and drew a circle aprox 6 cm in dia and in the circle she wrote 710.
Any Idea what it might be ??
Now you can open the picture
