G'day Max
That is the most extraordinary detective work.
For me this goes to the early development of the AUS lawnmower grasscatcher.
The point of interest to me is the cotton rather than synthetic covering.
Like the first Collect-O-Matic rotary catchers, it appears that makers moved to the new
synthetics - like nylon - from early cotton designs; as in Paul C's images in the second post.
Certainly, canvas (cotton) was used on grass catchers from the early 20th century,
but synthetics seem to have been used from the early 1960s.
I feel Max has uncovered the transition in technology here:
from Turner using cotton, then nylon and then moulded polyurethane.
It must be an irony that we have moved back to woven synthetics from
moulded catchers in the modern era.
Max, are these fair comments about Turner and grass catchers (in general)?
Cheers
