Removing the backing from my Lionel ABA Sharks screens, makes a better looking engine and took less then 45 minutes on all 3 units.
Looks like those 1984 Williams brass sharks.... The first ones to hit the 3 rail market....abeit correct from the frame up at least.
No. They're Lionel Century engines. Surprised with following post with this engine pics. wasn't noticed they were Lionels.
