Challenger Shaker hood question

[Hemi T/A]

Ive seen a few Shaker hoods that have a center rib in front of the opening , this rib follows along toward the front and stops where it widens for a Pentastar to be mounted on it , Ive seen another ( in pictures ) that doesnt have this center rib and is flat with no Pentastar . Is this a model year change ? or possibly a stock flat hood that was made into a shaker .

Challenger Shaker hoods came in three different versions.
1st Version: Without crumple zone creases, with center rib, and with Fratzog emblem centered at front of rib.
2nd Version: With crumple zone creases, with center rib, and with Fratzog emblem centered at front of rib.
3rd Version: With crumple zone creases, with center rib, and no Fratzog emblem.
NOTE: All Challenger Shaker and flat hoods have the center rib.

I realize this is a slightly older thread, am hoping you can help me. How can I tell if the hood in the pic below is an original shaker hood, or a cobbled-up regular challenger hood?

Any help is appreciated.

That new looking piece in the middle seems a bit suspicious - I don't know how you would tell if it is a repair or a flat hood made in to a Shaker.
Why does it matter to you?

Obviously a conversion hood. The rarity of the original Challenger Shaker hoods supports what @Steve340 said.
Be glad you have it!

My car isn't stock. I cut mine all up to clear a high rise Tunnel Ram with two 1050 Dominators. I stretched the hood opening 2", raised the height of the bubble 4-1/2" and opened up the nostrils 2-1/2" taller.

Thanks to all for the input, clearly it's not an original shaker hood which is pretty much what I expected (and fine with me). My plan is to finish it properly and use it on my challenger convertible. Which leads me to another question that will be a topic for a different thread.
