When my camera was in progress I asked Alan what his thoughts were regarding refitting red curtains. Specifically, would that service be limited to cameras that originally came with them?
He replied:
"As for red blinds, I will be pretty strict on that. Either the camera has red blinds or it was made at a time when red blinds would have been fitted. I’ve been offered money for red blind material. While I’m in business to pay the bills, some requests have made me feel slightly uncomfortable. Not only that, I spent a fair bit of time and money getting this right!
Alan."
As for what method he uses to create rubberized red curtains, he did understandably did not share that. 🙂
