Finderwinch Maxi handy windlass

[svskua]

Good morning everyone,
My 12 metre steel yacht has a Finderwinch windlass fitted, I cannot find any reference to this brand of windlass online.
My problem, is that I need to source a 10mm chain gypsy to suit DIN766 anchor chain.
This is to replace the 12mm chain which is currently on the boat.
I have built a new anchor chain tub and because I sail mainly single handed, I need to have a chain which will flake down in the tub more easily.
Also, going from 12mm down to 10mm should mean that instead of the 75 metres of chain that I have.
I should be able to carry 110 metres of the 10 metre size.
The Lofrans gypsy looks similar in pictures and if it is similar, I hope to adapt this to my Finderwinch one.
Any help and opinions will be appreciated.
