Dear Fer, David,
Your example could be named a cylindrical dial or polar cylindrical dial
if you refer to its shape and position.
Or point-sundial because the dial uses a point of shadow or light to
read the dial. I don't know how this sounds in English, it is a direct
translation of a word
John,
About the projection sundials you may read at my homepage.
Address below.
Use the link Projection dials.
It is an article by J.A.F. de Rijk, Netherlands, also published in
1986, 97, 1 Journal British astronomical Association. Equator projection
sundials
Best wishes, Fer.

Dear
All,
Could someone help
me with a definition of a 'Projection Sundial'.
- Couldn't find it
in the BSS Glossary.
- Folkard
Ward 1996 "Sundials Australia" have included in their section on Projection
Sundials - The chapel sundial (Merton College, Oxford), a Sun Compass
of a 'Projection Sundial'.
- Couldn't find it in the BSS Glossary.
- Folkard Ward 1996 Sundials Australia have included in their section on
Projection Sundials - The chapel sundial (Merton College, Oxford), a Sun
Compass, a direct sunlight through a hole onto analemmas on the horizontal
ground
