Hi
KyeI forgot to answer one question you had.
I believe the Clyde would have had a metal flap at the rear.
That is
speculation based on other designs.
I guess Clyde saw market differentiation.
But, remember, their approach was not remotely like the Victa
toe-cutter and its copies.
In many ways, Clyde 'jumped the gun'.
You had to cut the AUS wilderness before you could turn grass into lawn.
Australia was ready for Victa; not ready for the Clyde.
Clydes are rare; Victas much less so ...

Market acceptability only came in 1960, when catchers would be finally
accepted by the public. The rotary finally had street creds to overthrow
its nemesis - the reel mower. It won!
