Deep Sea Fishing Puzzler? Errol Flynn, or Howard Hill?

The Mail Bag brings this puzzler???

This picture, and a few others, have been linked to the 11-minute film, Deep Sea Fishing, with dates of the release of this short subject, anywhere from 1946 to 1954. There are supposedly some newspaper ads for the picture that listed, “starring Howard Hill,” not Errol Flynn.

Is there any information on the actual film, showing a correct year?  How about a date and place of it’s showing?

I leave this you Flynn Detectives out there …
