I know for a fact that Harold did not make headers for Layson. Layson's had a header manufacturer local to me copy a set of Spitfires and stopped payment upon delivery. I have seen the fixtures and one reference set. If there is enough interest, I can get them made.
I see. I saw pictures of the Laysons headers and they looked like Harolds. I just thought he was making them. He needs to patent them so people won't copy them. Mike
