Old Boson Whistle Paid ten cents at a garage sale

Hi to all, I scored this whistle for cheap and have never seen this mark by itself before. Usually it has other marks with it, this is just marked SILVER.

I was curious about the age, country of origin, metal and any other info you could give about it. It is 2 5/8" long and very high pitch, the dog does not enjoy it.

These pictures will explain it all.

Thanks
