Noodler's Neponset music flexible nib fountain pen

Hi,
Here is the Noodler's Neponset flex pen with music nib. I got it from purepens the day they announced it. Even tho I like tinkering with my pens I could never make this pen work 100%. It writes and it flexes, but it also railroads...I probably have pushed it too far and sprang the tines (see photos attached). If you know how to heat set the feed and up for a little tinkering, then this is the pen for you. I will let this one go, so I could get some vintage flex.
Color variety is called : Forbidden city (it is pink&purple)
Filling mechanism works 100%
I comes with a box (no instructions)
Feel free to ask questions, I will answer them asap.
Thanks for looking!
