Thanks for the additional photos! My recommendation would be the Series 380 or Series 385 based on what you show here. The important difference between these two Series is the depth of the bottom fitting as shown in the image below. You will also need to refer to the stamp on the metal channel to determine what spring strength option to select. As for the sash lock, you can start by comparing your specifications to the 90-180 and 90-077A to see how they match up. Comparison of the S380 and S385 balance shoes.
