Hello wce and Batimus
I have to agree and say this is a rare kick-start Model 22.

But options are there ...
So, the kick start mechanism has been removed at some point.
The two base anchoring points survive.

This goes to provenance and it may not be compelling to restore
the mower to its original state.

The story is probably that, as spare parts dwindled, the
owner took the obvious step (pardon the pun), and used a lanyard.

So be it.
It's part of the charm and history of old lawnmowers.
The thing is, history knows what happened.

Cheers
