Does anyone know how to thread a Singer Merritt 2440 Sewing machine?

Question

If you know of an online manual that'd be appreciate also.

Answer 1

2404 perhaps?

EDITED TO ADD: Try the 2404 threading diagram anyhow... it's likely to work.  There are generally only a few threading paths in any maker's line.
