I'm sure I would have had at least 15 Aldi mowers and all came with newish catchers but I prefer plastic catcher's to bag catchers so all the mowers that you just rivet the Victa
Back flap onto the base and fit the plastic Victa catcher I would get rid of the original bag catchers.

I still have 3 spare Aldi catchers ,2 Aldi plastic catchers and one Aldi bag catcher.

Cheers
Max.
