It looked to me that the length was 28 3/32" the depth was 1 3/32" and the width was (measured on the top of the balance, where the spring can be seen) 21/32". the number listed on the balance was 740. pictures are included.
Thank you
Gary

Hi Gary. For a winged balance with a 1-3/32" shoe depth, see our S385-28. You will need a stamp option of 2740. Many thanks.
