the chair is not part of the set- other than it probably fits well under the cabinet. you can visit the singer site, enter the serial # and see what year it was 'born' my 15-91 was built in 1949. it looks like a nicely maintained machine. they originally came in a 'carrying case' so the cabinet is something an owner picked up & put the machine in. my cabinet looks nothing like your cabinet- older & not in such good shape. that cabinet looks a lot like the one my aunt's White sewing machine is in- she bought that machine back in the 60's- it is nice- a great buy- congratulations on winning the auction- they stitch the most wonderful straight stitch...
