Hi Mike, I saw a small screw attaching the disc and assumed it allowed a longitude adjustment. If it is just an attaching screw, perhaps the owner could drill and tap a hole suitable for their longitude and even DST. The EQT graph is universal with no longitude offset. I believe the similar dials that Tony made for his grandkids were designed to be universal.

Unfortunately, the authorities refuse to change the clocks at each equinox, so there would be some offset. BTW, I have one of these “Tony Moss equatorials” and mine is adjustable for latitude, but not longitude as someone suggested.
