UCC28740: Flyback Transformer Design

Part Number: UCC28740

I have simulated a power supply using TI WEBENCH  as follows:

VinMin = 210.0V
VinMax = 240.0V
Vout = 15.0V
Iout = 2.0A

further i am using two more components for 18V and 5V supply.

and for this topology following transformer details are given : (see attached pdf)

Core=TDK ,
CoilFormer=TDK
Core=B66311G0000X127 ,
CoilFormer=B66206B1110T001
Lp= 829.0 µH
Turns Ratio(Nas)=
17:14
Turns Ratio(Nps)=
124:14
Npri= 124.0
Naux= 17.0
Nsec= 14.0
TDK_B66305 302

I have contacted coil craft, i get refusal from them in negation. all my schematic and pcb ready except 
Can someone kindly let me know from where i can get this transformer get manufactured in Germany.

Thanks.
