OK Gang, the idea is this. I will start with a clamshell model and the next poster will give at least one cobrahead that the clamshell glass will fit in. For example:
Line Materials Ovalite
Which model cobrahead will this glass fit?
Answer: ITT/American Electric 25
So, I'll start with an easy one; which cobrahead luinaire will the glass from a GE Form 400 fit?
