Alexander P. Hatch American Whistle Patents, Antique Police & Bicycle whistles 1899- 1902.

Two important American whistles long searched for by whistle collectors
were found April 2019.
Alexander P Hatch Patents were thought as none existing, since none were seen and the patents applied for stated no model examples.
As to rarity we know of another Plural whistle I discovered with a long time U.S.A collector in 2016, The Police one is the only example I know of.
I imagine there are more to be discovered and there is a good chance that the more fancy variation with few combined whistles as seen on the same patent of the plural whistle is somewhere out there… (so it is with the British Plural one that I posted the patent for last year, no actual example ever seen  – it is from the same period)
keep your eyes open it is a treasure probably worth well over a 1000, hopefully with more exposure to the ones that just surfaced more will show up in the future.
It is a pity that there is no information about this inventor who was a citizen of Bridgeport Connecticut at the time, I am sure an extensive research can reveal much more as to his life,  Albeit the fact that his whistle patents are among the most cited by whistle inventors, dozens of newly patented whistles since then quote his patents, including 21st century ones.

Samuel Auld The Greatest Glasgow Whistle Maker. A. Strauss

Samuel Auld started making whistles in the earlier part of the 1870s, after Joining Westwood (See another article about a previously unknown maker J. Westwood which I found)  Auld partnership with Westwood at Globe Brass foundry  248 Gallowgate st. (Both were the sole partners dissolved on July 20 1877 and announced legally 31 October 1877.
Very few are known to exist, and each one is numbered on the side.
These are the only numbered police Snail whistles of this era.
The original numbering suggests that there were about 300 made
Highest known number is 369, as of now 3 or 4 are known to exist.
