I am sitting here thinking about this and just remembered, I grew up in SW Washington and one of our haunts was the Lewis River and we used to go fishing up there a lot during the summer. There was a world famous fishing pole company in Woodland and I remember vaguely there was a small company that sat right next to the fishing rod company that had a sign up along the Hwy and it Said "We can make your boat an open bow boat"
Now remember, this was in the late 70's early 80's so we are going back over 40 years ago, can't remember their name, but they were there for a few years.
I am starting to think this may be one of their boats that they converted.. I also remember seeing some Mirrocrafts they had converted back then.
I started thinking about this, because that is a WA boat based on the numbers on the hull.
If you look at the pictures above the bow on this boat in question, the drivers side cut at the junction of the angle aluminum at the front has a dent where the two pieces come together, which is a sign that they bow was cut out with shears and not a saw. I have had that happen on RV siding when working with aluminum sheeting.
