[QUOTE=Charlee;4846807]I can't tell you where it is on the Athena, but the 401A serial number is on the underside of the machine, near the needleplate. Should be two letters, followed by six numbers.

Thank you! I don't seem to be able to get the bottom plate off the 401A but will try asking the Singer repair guy tomorrow before I try forcing it. Happy new year, Charlee. I always enjoy your informative postings.
