Thank you for your reply, I have seen the resin plates I think it was on the CPL stand at Bristol in January, but they didn't have the pattern I required. I think would be ok for the job in mind but I looked through their complete range and no luck.If you can't find brass or nickel silver tread plate Archer have resin tread plate as surface decals. There are various types available. Archer Surface Details
I've their resin rivets with no problem.
Tried them, and no luck .You might try CPL. I'm not sure, but I think they did some...
