I ordered a keyless flute in D from Rob Forbes in August, 2014. I received it in January, 2015. So, the waiting time was about 5 months.
It is made of Delrin. It is tunable, but its headjoint isn't lined. I bought a soft vinyl pouch from him, too.
I think it's a loud flute!
P.S. I sold this flute to my friend in 2015.
