1948 - Rocket Whistle by Trophy Products

[Joe K.]

As seen in this Winter 1948 N. Shure Company Wholesale Catalog: 

 

Note that the word OUT is where the price would normally be, indicating that that item was out of stock. Perhaps this whistle was a carryover from the previous year's catalog listings, so an earlier date is possible.

I also came across this Worthpoint image of a full box of the whistles where they are called the "Tri Tone Rocket Signal Whistle".
