This looks to me like a New Home machine - This would have been made before New Home was acquired by Free.

It's so common to get attachments with a machine that don't belong. But it's always nice to get a set of Singers if you get set that doesn't fit.

I'll add - New Home and National both made machines that have a strong resemblance to machines made by the other company. However, so far in all of them I'm checked, they used a proprietary top tension, and the attachments are not interchangeable, nor is the needle slide plates.

If you look for attachments, you have to get those for New Home earlier than when Free bought them. Free continued to use the New Home name, but the machines are not similar to those made directly by New Home, they are in fact Free machines with a badge name. Attachments for a Free made New Home will not fit your machine.
