1937 -1940 casement window rigid screen parts & mesh #1

Thanks for reaching out to us, Paul. From what I remember working in the younger days, to replace the screen cloth you will need to pull out a type of "metal" spline from the screen frame and I don't believe it can be re-used. I would suggest using one of our foam screen splines we carry in various thicknesses. Our selection can be found here. 

As for the screen cloth itself, we carry it in a few different sizes and types. Take a look at the 45-036 in the fiberglass, the 45-736 in the invisible fiberglass, and the 47-036 in the charcoal aluminum. As for the clips, the only Wicket type clip shown in your photos would be the 70-091 which is 7/8" tall. We also carry the newer style "Z" clips like the 70-057. The "Z" clips we have them in various sizes; see our full selection here. Review the specifications for the parts we've related for you and see how they compare with yours.

I'm afraid these parts are the best we can offer. I am very sorry that we cannot offer a suitable replacement option.
