Sundial of the month December

Vertical sundial
Oriole House, Eindhoven

This month, we show a vertical, west declining sundial. It is made of stone, and has a large metal sun with sunbeams in its centre.
It reads local apparent time from IX hours am until IV hours pm.
The polestyle is the bottom edge of a thin metal sheet.

On somewhat closer inspection, it looks as if the style origin is not exactly over the XII-hours line.
However, the hour scale lies more forward than the metal sun where the pole style enters it.
The mathematical style origin is therefore up and more to the left.
