I own an Old - but Great Delta Combination Wood / Metal Lathe. It is a 48" Cast Iron Bench. I'm Guessing it was made in the 1930's or 40's. I can not find a model No. but the Serial No. is 33-3820. The Name Plate says Delta - Milwaukee. I also have a same vintage Delta 10" table saw/jointer/router and you found and sent me the Owner's Manual. I hope you can do the same for my Lathe because I Love it!
