Missing bimaneg masks

Hola!
My BIMANEG carrier (laborator L900 with CLS 450 head) didn't come with the masks or anti-newton glasses. I will try to make the masks for 35mm, 6x6 and 6x9 from scratch, but...

Does someone know their thickness? (or height) and rest of sizes? (in inches or mm). I guess they are metallic..

Any information will be very appreciated.

Thanks,

JuanMi

Google will find you some photos of them, there are metallic, you can even buy one of them from BHPhoto. You can cut them from thin mat board and paint the cut edges black. Not sure on the thickness tho, but older neg carriers for the 606 and 659 used 1.5mm glass.

Thank you, Bob. I will check BHPhoto!
Greetings!
