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
