Dear friends, I am sorry to have to announce that there never was
a typical organ grinders cap in the Netherlands. In the thirties and
forties of the 20th century many people in the Netherlands were
wearing caps (sing.: pet, plural: petten), but they were not typical
for organ grinders. This model is, of course, way out of fashion, so
they may be difficult to obtain these caps even in the Netherlands.
I know of some English caps which come very near to this model, so
maybe they can be ordered there.

P.S. Thank you for sending MMD again! I missed you!
