Hi there Roberto. 

I'm afraid we can't be certain with the bottom shoe being damaged. The S351-33 and S390-33 come to mind but you will have to measure the depth of an undamaged shoe to confirm the best match. Based on the 33C stamp, you may be able to use the 3230 stamp. A pair of balances with this stamp will support a sash weighing 18 to 23 pounds but you can weigh the window sash to confirm it falls within this range. 

Please let us know if you have any questions!
