A quick learner from Williamsville, New York says:
Please see attached photos of the snap in glazing I have in my casement windows. Please identify and suggest a replacement if possible. My windows were manufactured in 1975 and have know identifying marks or numbers on them.

Thanks for posting. I'm afraid I'm not familiar with this glazing. Take a look at our 55-156 and see if you could possibly use this as a substitute. It was used by Wenco windows. I'm not sure if it will work but it seems to be the closest possibility we have.
