So what Jagdgeschwader did Bentley fly in during WWII?
I suggest you take his drawings and try to fit the MW tank into the 190S.
Not claiming your wrong in this case but you said the same baloney about the 115 liter "cruising tank" (as the pilots call it) in the FW-190A8. I am saying I would like to talk to the Museum and the guys who flew the FW-190A are crystal clear in the fact that they had and used MW.
To further clarify what has come out regarding the 115 liter tank are the JG Technical Officer put out whether it was to be used or not and was mounted and dismounted as needed. It took less than 5 minutes to install and remove it according too:
1. The men who worked on the FW-190
2. The men who flew the FW-190.
Looking at the instructions in the manual the most time consuming part of the job was undoing the half turn flush screws in the auxilery tank removal hatch.
It was not a very popular item (weight) but was used on occasion. Yes it was marked when installed and the sticker removed when the tank was taken out.
