Greyhound Model 30 by Newhome. Not re-badged machine. If you search my posts you'll find the one I did about it. Another member had acquired one just like mine and we compared notes.
\This one really doesn't need a dust cover as it's got the complete box. Newhome was autonomous up until the 20s or 30s then they merged with Free. Later on Janome bought them and the Newhome name continues but under their umbrella.
At least that is what I remember reading. I could be wrong.
