G'day
NormMany thanks for the link.
I had not seen that one (typical).
This is a S-S side grass catcher, probably linked to a later
Supa-Swifts of the late 1960s and 1970s. But this is not clear.
This catcher is important for the development of early rotary catcher designs.
Supa-swift offered a catcher from day one - with the first model of 1959.
This puts SS at the forefront of early rotary catcher designs.
This catcher did change slightly over time ... Subtly ... in the venting.
The early catchers appear to have had poor venting; but SS learnt from this,
with louvered and, later, round-section mesh features.
I'm not sure about the dating - because of the subtle changes.
This does present as a later version ... I think.
