not sure if sewing machine is valuable
 

Hi - new to this - wanted to see if a sears Kenmore model # 1433 zig zag sewing machine is an antique? The wooden table it is stored inside looks very old. Thank you!

nope - Japanese made machine after WW2. the three digit prefix would be helpful in determining the manufacturer. They sell in the $25 - $50 range depending on the attachments/cams and other stuff you have with them.

It is very possible that someone took a much older table and put this machine inside it. My mom did that with her White - she took out the 1930's machine and put in a Japanese made zigzag from the 1960's
