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
