Where do I find serial number of Singer 403a?
I thought knew where to find it but obviously not unless 172176 is it. It was underneath. Also, I've lost the Singer site that list all serial number (not Isamacs). I've searched this site but can't find any reference to Singer site.
Somebody please help. My daughter just bought me this 403a in a beautiful cabinet for my birthday and I'm trying to date it.
