I believe your white operator could be the 39-388. Take a look and see what you think. As for the other photo of the bronze handle and cover, that does not look familiar to me. The handle could be the 39-205 but the cover shape is not familiar. See if you can remove the cover to expose the operator itself. Maybe that could help us identify the hardware. |
