Hello,I found this Durkopp D12,I got it because I was very curious about it.I have yet to compare them well,for now I only noticed that the Durkopp seems to me slightly larger and heavier than the W&W (but to be verified).Who knows what needles it uses I couldn't find any information on this model.I don't have much time these days but it will be interesting to compare them.
