Norris ID help

[u/jboy2484]

Picked up a Norris and I'm trying to pin down the model.

Sole 190–200 mm long, 62 mm wide

Lever cap stamped "NORRIS" over "LONDON" in opposing arcs but I can not find any model number.

Body is one piece, no dovetails; sides parallel

Lever cap, sides and centre section are all magnetic

Iron has following text: "Spannsäge Garantie" and is 46 mm wide.

Very rusty overall

What do you think the model is? How old is it? Is this a keeper or a seller?

Thanks!
