I noticed that my ClearProp F-86A-5 has the engine face with a round dome.

All Sabre J47’s that I have seen have a cone that looks more like a bird’s beak. Which seems logical when looking at the intake tract.

A quick search on the internet showed J47’s with more traditional cones but were they used as such in early F-86’s? Was “the beak” a later development/block of the J47?
