Hello bigwids
This is a version of the Model 45.

In the Blue Bar (above) type: -
- Model 45 Craftsman, and then;
- Model 45 Lawn King.

My best guess is that it presents as a Craftsman.
[Assuming the catcher and colour are original]

The Maker's ID plate should give the game away.
[A close-up of the Model Number would help.]

Hope this helps.
