If you could put up a few more images, that would be great, as well as any numbers and words on the engine, sides, hood, or anywhere.
Seems similar to this in my mind, have a look and tell me how close you think i may be:

I can tell you this about the mower in the picture i have put up:
12.5 hp Engine
Friction Drive
Electric clutch for the cutting deck
Heel Toe operation
40" Cutting Deck
As for the age, we may be able to help more with a few engine details you can give us.
I'm guessing its a briggs & stratton engine, somwhere on the cooling cowl of the engine (the metal cover bolted directly to the top of the engine) you will find a series of numbers stamped, if you pop those up, we can tell you a fair bit more about the engine, including its date of manufacture, whitch will give a good indicator as to the age of the entire mower.
