The AB090174 serial number was assigned to Singer's model 31 in June 1926. Thus the actual machine would have been manufactured before the end of August 1926 (when Singer assigned another set of serial numbers to the model 31 line). The machine was built in Elizabeth, NJ. This site shows when the serial numbers were assigned to the AB series: http://ismacs.net/singer_sewing_machine_company/serial-numbers/singer-ab-series-serial-numbers.html . To look up other serial number codes see: http://ismacs.net/singer_sewing_machine_company/serial-numbers/singer-sewing-machine-serial-number-database.html .
I hope this helps.
