Hi JoshuaF,
Have a look for the tag in the same spot but on the inside of the frame. It may be hard to spot if it's been over painted. Your Atco looks to be the same model as mine 1955/56, the clutch is fairly simple just steel plates that are pushed together to produce a drive chain.
Are your clutch plates loose in their housing ? When the lever is moved do they tighten up against each other ?
In your photo above the collar behind the spring looks like it has moved, shiny metal on the shaft.
