From the 60's I can find little about it, however, from the other machines in my collection I see some interesting combinations. As with all product development from any period everyone borrows from everyone. Aside from being just another badged Japanese machine it has distinct Brother likenesses. The most interesting (and unique for the Japanese machines) is the Necchi BU presser foot lift mechanism; it's a very near copy. The presser foot tension control is also similar to the BU.
I tried it out on a little practice piece... I think its more quiet than the BU? I'm going to keep working with for a while; I love quiet.
