Identify parts and find a source to purchase.

I have what I believe are Pella Screens and have been able to rescreen them but some are missing some parts.I hav included pictures of what I need. The missing parts are the clips on the top of the screen and the pull tabs at the bottom. Any assistance you can offer will be appreciated. The clips I need look like the Anderson Replacement Screen Clips Product Code A-087324 listed on your site. May by these are Anderson Screens? Thanks looking forward to hearing from you. Mike Novotney
