Wow, Charlee - your knowledge on the old babies is amazing. Thanks! I'm relieved to know I don't have to dismantle the lower casing to look further for the serial number.
How did you know that, besides your extensive experience? Is there another source for such information?
There has been a posting lately about getting a certificate sent to you from Singer showing your machine's 'birth' year, so it'll be interesting to see what designation they give my 401A.
Thank you! I appreciate your helpfulness.
