Hi guys, I've just gotten my machine back from getting the blades sharpened. I've taken a photo of the engine numbers on the side of the B&S. Hopefully this might help someone give me a better indication of age.

I've done the photo in \negative colours as it's almost impossible to see with a normal photo. Here are the numbers anyway:
Model: 60102
Type: 0302 01
Code: 6906091

Any help is greatly appreciated!
