431 on the left here, appearing to dwarf the 411 in the table: ) (It’s an illusion)

Bought as a spares machine for my other two 431s, but it still performs amazingly well, despite that: )

Came with no drop-down extension plate, paint bubbles & the throat plate fixings are minimal… Skeletal even, with only one prong (of four) on each side: ) But it can still do double needle zig zags at full speed. Not recommended, but it does it. I bought a replacement drop-down table for it, but it’s from a 600 machine & white rather than beige. But it fits & works well: )

Skeletal fixing pins here: ) But adjusted thus they do actually work: )

Note the 503602 hooked bobbin case here. Necessary for chain stitch on 411s & 431s.
