please could anyone ID this lad? I doubt it's an endli due to its upper jaw features. Any input would be much appreciated. Cheers!
Grateful for assistance in IDing this polypterus

Your fish still has a lower jaw that protrudes more than the upper jaw, it's just not very pronounced or exaggerated. Closer to matching but it still sticks out a little - still looks like he's pouting. 
Hybrids and captive breds in general can have a wide range of appearances.
Here are 3 upper jaws for comparison - one you can't see very well because it's head on, but the upper jaw is notably over the lowers in the other two.

Appreciate your insights, very helpful indeed. Would you say that my fish is an ansorgii/endli hybrid? And yes it doesn't have the most shapely head - may even be slightly deformedYour fish still has a lower jaw that protrudes more than the upper jaw, it's just not very pronounced or exaggerated.

If Hao says it is then I'd take his word for it.
I don't think your bichir has an upper jaw bite. As for the headshape, I've noticed underfed bichirs will start developing weird headshapes/big eyes (mainly seen at LFS). Assuming you just got the fish recently. The headshape should change over time as it grows bigger.
