That's a good question.
I have not recorded any Clyde rotary with a catcher.
There may be good reason for that.
It's odd but ...
- Reel/Roller mowers included the catcher in the price.
- Side-wheels made the catcher price optional (these were front or rear)
- 1950s and 1960s rotaries made catchers price 'optional'.
My best guess is that most Clydes were bought without a catcher.
Therein lies the problem.
