Congratulations: You have found a seldom seen Blackhawk SS Special, and become one of a very few owners of that particular model of Blackhawk.
I have one myself, and since I purchased it, I had never seen another one; not even in pictures.
I'm it's second owner; it belonged to a Blackhawk employee who got it in lieu of some part of his salary, when Blackhawk shut it's doors.
When I got it, it had "never" been paddled. I've used it a couple race fully but at same timeof times, but only on deep water lakes, and as a result it is still in pristine condition.
Mine is the same color as yours, and has the same ash/mahogany trim. It also still has all of the original stickers attached.
I have 7 other Blackhawks besides my SS Special; an Ariel, Nighthawk, 2 Shadows, Covenant, Zephyr, and Proem.
Previously owned a Shadow 14, Starship & a Combi. Unfortunately, I don't have a good photo of my SS Special.
