Hi Byomarimba
I am not 100% sure about this, but I think you may have a ATCO Lightweight of a roughly 1950-54 vintage.  
The way you start it is a kick starter - you still have that bit.  Its just to the right of the exhaust.  
Here is a good picture of the starter
And 
this is a video of the mower from youtube
I don't know if it had a catcher
