  This

  the Latin motto, and the green foliage (that looks

  circa 1920.   It could be some sort of souvenir
  from a museum shop.
   
  By
  the way, plumb-bobs with little storage holes are
  found on some ivory diptych sundials of the 16th
  century and later.

Subject: Genuine or not?

Hello!

There's a diptych sundial on sale for about 80 euros supposedly dating from 
1920.

Do you think this is genuine? I think it is a modern replica.

http://anticariatulnou.ro/diverse/antichitati-artizanat-colectionabile/cadran-solar-cu-busola-antica-din-lemn-diptic.html

The string does not seem to be adjustable for latitude, I see only one hole 
(it's fixed at 42 deg.). Why then go through the trouble of printing the 
latitudes for European cities on the back?

One thing I find interesting is the plumb bob and the orifice on the vertical 
plate. I think it is meant to align the piece to the vertical. I haven't seen 
this before.

Thanks,

Dan Uza

Compass doesn't look quite right - if it's German I might expect East to be
written as Ost.

Re: Genuine or not?

It doesn't seem genuine to me.

It isn't just that there doesn't seem to be a way of moving the upper end
of the string to the other latitude-marks. It's also that you can't just
change the angle of the gnomon, for a different latitude, and use the same
hour-lines.

So there seems to be no purpose for the latitude-marks on the inside of the
vertical,  piece--other than to make it look adjustable for latitude.
