Your machine is a 127. It was manufactured in 1929 between March 6th and March 8th. It's serial # is clooser mto the beginning of the run versus the end so I'd guess probabbly the 6th or early on the 7th. There were 15,000 manufactured in that batch of 127s. Check out the Vintage Sewing Machine Shop here on the quilting board - it's dedicated to all the old ladies (sewingmachines) that are saved plus there's a ton of info on that forum.
