Thanks Doc & Tim,
I must still be inartful in my question. What you are showing are the faces of the selectors that tell the operator which tank.
What I wanted to see are two items:
First is the insides of those selectors. An IPB (illustrated parts breakdown) of those selectors showing mechanics, and electrical schematics.
(Of course, I understand that IPBs were rare in the mid 30's. Mfgr's equivalent will do.)
Second, a question: Is an IPB (or equiv.) available of the actual valve that opens and closes a particular tank, including its electrical schematic. Is it a disk, or a cone, or a block . . . etc. I want to see the mechanics of the valve.
I suspect that since Lockheed Burbank did the modifications for long range to EA's c/n 1055 (and c/n 1065, the "Daily Express) that the actuators on the added tanks were the same as on the standard tanks -- or maybe not? Must have cost that publishing company a few simoleans to get all of that extra tubing installed. Tubing is a b***h.
Anyway, all suggestions will be appreciated.
Thanks
Mike
