While doing my usual eBay whistle check and found this Low D whistle
I have never heard of Dorman whistles, there is no reference I can find on C&F, and the internet comes op with a Canadian automotive company making deer whistles.

Nice find Davy, looks nicely made, hole pattern seems unusual (to me anyway) tiny holes at the top, big space between bottom two holes.
Was considering going for it (needed to open an account first) but it sold seconds later.
Any info on this whistle would be much appreciated as I decided to take a punt on it!!! Does look well finished and hopefully is as good as the pictures make it out to be…
Hope it’s a good one mate, do let us know 
Now have the whistle and am well pleased with it. The finish is excellent. It has quite a breathy sound which I like. If any more came up for sale I would certainly recommend them.
