Pocket Sundials

[jeffrey degenhardt]

While surfing the net a while back, I came across a museum site that
offered a couple of pocket or wrist watch type sundials for sale in
their shop. Of course I did not mark the page and I have not been able
to find it again. I was hoping someone could help me find either that or
another site again. These items were not very expensive as I recall,
about $50-$80 U.S.
Thanks for any help.
