Pepe,
I have 3 FDG P-51b or c models. (FDG_P-51b, FDG2_P-51b_CFS2, FDG2_P-51c_mh_fs9) I am pretty sure the FS9 Malcom Hood is a birdcage. I am quite sure they were all free releases of their former donationware models. I have paid for some of their work, but not the Mustangs, if my fading memory serves me correctly.
Send me a PM and I will get all three to you.
