Yes, the attachments are for the Moser max50 machine.
I have had the Moser max50 for several years and bought exactly these attachments.

I use the attachment comb set for the Moser max50 machine.

Hello,
As far as I know, these combs also fit other Moser machines. I have compared the colour code of the combs supplied to the colours in the set. For me it matched.
I hope I have helped you.
Kind regards Bob
