I see 1930s art; like what is found at RCA building in New York, Noguchi works.
The threading on this is like my National Two Spools, just that your Monty has a cover. My Two Spools takes a 15x1, and if I remember correctly is the only National machine that does. All the other Nationals use 20x1 needle.
Cool looking for an ugly machine!!
Nice find! Enjoy!!!
