This article is just a glimpse and a part of Part one in a very long 7 part research into this type of whistles, consider it a first draft , There are MANY more which can be accurately dated and way more which I could not yet accurately date
but as a draft it may inspire others and you may send and email to firstname.lastname@example.org to add ask contact.
I would try to first cover mostly British 19th Century and some whistles of other countries without going into many details, since some countries deserve another article.
Part one is a draft and 19th Century General Time line and whistle designs.
