the last Necchi (japanese made) I got came in a really nice Singer cabinet. I took it out and put in a White (Japaneses made) and it fit right in. The White had previously been in a Singer trapizoid cabinet.
I looked at my Italian made Necchi, and it looks like it would fit in a Singer cabinet -however it takes up the whole space (like the 401 does) so you need one without a lift - or with the lift removed. I really like the lift mechanism the older Necchi has!
You can always do like I do - stack them out in the boat shed (lots of room since we sold the boat).
