Thank you! Now, your top attachment is winged, while your bottom attachment is non-winged. We do not have an existing Series to match this combination, so your balance will have to be custom made.
I also see that your stamp is marked 27 9. Like the attachment combination, we do not have a corresponding stamp option to match yours. Before we can get started on the custom order, I'll have to know what the weight of your sash is, so that we can determine the appropriate stamp! You can find this out by removing your stamp from the window and weighing it on any common bathroom scale.
