Hi MF, and all,
They stopped making the 24 about 5-6 years ago(am happy to stand corrected) and parts are a real PITA to get for them.
I've had 6 blade carriers for them on back order since last April (yes, almost a year and a half ago) and the response from Victa is always the same, "yes, they'll be here in the next 4-6 weeks".
