I have determined what balance I need, but for the option choice I am having difficulty. on the balance I have all I can find is the following: 32 4 CALDWELL GM

3240 would usually be the option for a "32 4" stamp. Verify that by weighing the window sash. It should come up between 23 and 28 pounds.
