It might help if you can show us a photo of your model.

Also, unless there has been a recent rules change, you don't need a photo of your exact P-47 prototype to compete in the Pro Am/ Sportsman class. All you need is one photo of any P-47D razor back. Remember, your model won't be static judged like the Expert, Team, Advanced classes where full documentation is required. It's up to you as to the amount of "proof" you wish to provide ( in your class ) because the judge only needs one photo as "proof". It's "All-or-Nothing" in the Pro Am/ Sportsman class. You get 25 points whether you provide one picture or ten. If you show no "proof", then you get zero points.

You can also use plastic model box-top artwork or any other published illustrations as your proof.

Congratulations for qualifying and best of luck!
Ken.
ps; a little friendly advice, make sure you practice your routine in the next couple of weeks. Go through the model thoroughly checking all servo mounts and pushrods, engine & muffler, cowling & canopy screws, wheel collars are tight, retracts & flaps function correctly...etc. Practice flying WITH your caller next to you just like you will at the contest.
Install a new glow/ spark plug & put a couple flights on it before the contest. Equipment problems are much too common at scale contests and shouldn't be if you "rehearse" everything at home in the days leading up to the event. Check all your batteries as well. Equipment failures are the last thing you need to think about while you're flying at the Championships.
....and most of all....remember to have fun!
