Thank you for reaching out to us. Most Lawson windows use the Series 385 which comes attached with the 19-005 top and 15-004 1-3/32" deep bottom fitting. I recommend you measure the depth of your bottom fitting as shown below to confirm. You will also need the 3530 spring strength option for your replacements.

Let me know if you have any questions!

Hello: It appears the bottom is 1 inch wide as there is no way 3/32 could have worn away even though 25 yrs old.
Let me know what to order
Thanks

If the bottom fitting is 1" deep, you'd want the S380-36 with the 3530 spring strength option.
