Hello Sundial List,
I've had a reply from Fer, but he somehow didn't send it to the List.
With his permission I append it here.
Best,
Mac Oglesby
P.S. A couple of years ago I saw an advertisement for the large
Glynne replica, but when I ordered it had been discontinued and was
not available. Does anyone know where large (about 11 inch diameter)
Glynne replicas may be obtained?

Hi Mac,
A shop in Amsterdam sold authentic ship models and all kinds of ( more or
less ) related things.
Around 1980 they also wanted to sell ( portable ) sundials and I gave them
some help for the patterns.
There were some good examples but also some of less quality.
Than came the question how to make a copy of the Glynne dial.
This dial is in the Smithsonian Institution in America.
Some very good technical fotgraphs of the dial were taken and I took the
task to make a new drawing of this dial.
At that time I didn't have a computer and I drew the pattern all by hand.
It was on a vacation to the parents of my wife Sietske.
This drawing is used to make copies of the Glynne dial and the production
was made in Taiwan. In our country the costs would have been to high.
With the production I had nothing to do, my job ended with the drawing.
2 types have been produced, one with 30 cm diameter and a smaller with a
diameter of about 15 cm I think.
In the production some went wrong.
They had good drawings and a good discription but telling to the people in
Tawain failed at some points.
In the example I have the height of the style isn't fully correct and the
width of the style triangle is less then the space between the two XII
hourlines.
In the original dial a tickmark was drawn for each minute.
I tried to do the same but irregularities were seen and I decided to draw a
2 minutes division.
The callendar for the EoT table still is the Julian callendar.
In England the Gregorian callendar was in use many years later then 1582.
Somewhere in the papers in my room some details of Glynne must be, but I
have no idea where to start to find that and I haven't the details in my
mind after so many years.
It was fun making the drawing once, but I won't do it again.
Best wishes, Fer.

Subject: Glynne dial surprise
Hello Fer,
I recently purchased a sundial from a mail order catalog which was
advertised as a replica of a sundial by R. Glynne in the 18th
century. The replica is a brass disk about 4 5/16 inches in
diameter, mounted on a marble base of about 5 1/4 inches in diameter.
The brass gnomon is a pierced triangle about 1/8 inch thick and an
angle of about 52 degrees. A sticker on the base says "Made in
Taiwan." The information sheet packed with the dial says "Authentic
Models (USA) Inc., Creswell, OR 97426."
The dial plate is beautifully drawn and etched, with an astonishing
amount of detail. However, I noticed the gnomon had not been mounted
properly, for it did not intersect the dial plate at the line for 6
AM and 6 PM, being displaced about 1/8 inch north. Thinking it might
be possible to adjust the gnomon, I removed the two tiny brass screws
and took off the gnomon. There, where it had been completely hidden
by the gnomon, I saw, in letters not much larger than half a
millimeter high, "F J de Vries 1982."
Surely there is a story behind this. Won't you kindly share it?
Best regards,
Mac Oglesby
P.S. I don't think I'll be able to change the gnomon position, but
the dial plate is so lovely I believe I can live with that small
problem.
