Here is a comparison of the front end of a Pennsy BP20 (left) and the front end of a BF16 (right).
The BP20 is a Weaver passenger Shark and the BF16 is a Lionel freight Shark. The Weaver's color looks closer to DGLE.
Both are nice looking units'. The Weaver appears to have a better fit and finish. The Lionel appears beefier. I wonder which one is the more prototypical?
