Identification help please

Hi I was up in the Yukon this past month and saw this boat. Reverse image searches have not helped.
Can anyone give any clue as to make or general year this was made?

I think they were made in the 1950s or early 1960s. By who, I don't know. They were common. I remember them as harbor patrol boats with a Chrysler Crown gas engine.
