In an email, Mark field said "I have enclosed a photo of an HH-53 on alert status on the flight line at Woodbridge around 1981. This was tail number 69-5797. I was her Crew Chief at the time."
Here's Mark's photo, which I made a little smaller to fit the page, with another version, below.
HH-53 tail number 69-5797 on Woodbridge flightline, around 1981.
Then I got to tinkering with it a little, and converted it to this:
