I have an Arri 650w fresnel but without a barndoor. Does anyone know where I could get a substitution? The size of it is 6"1/2 - 6"3/4. I dont want to get a new Arri barndoor, it just cost too much. 
I wonder if the Rostronic's barndoor or any others would fit?
Your help would be appreciated.
Thanks
