know your place foo!**
A: Well, there's the Z-95 Headhunter which a civilian and pirate favorite. It looks like an X-Wing except no s-foils.
Then the X-Wing comes. It... looks like an X-Wing. The Rebels use it throughout the Rebellion and New Republic.
Then we have the XJ-Xwing. Which is a new and pimped out X-Wing that the Jedi Order was using at the time of the Yuuzhan Vong invasion. It is basically an X-Wing but new technology and junk.
I'll throw this one in, but we could argue whether it is an X-Wing precurser or not:
ARC-170. The only reason anyone says it's an X-Wing precurser is the S-Foils, but it really doesn't look like an X-Wing. It's big and looks clunky, but it does have a rear gunner which you would think would be able to keep things off their back.
The last bit can really be arguable.
Since I don't know if this is to your satisfactory, no question asked.
**Again... not being serious :/
