Are the jobbers under the left wing duplicated under the right?
Nope, just a couple of protrusions of some sort under the right that are "hidden" by the fuselage. As far as I can see what is on the left wing is the same as the right....the stuff you're referring to is coming out of the nose.
They look like early experimental rocket rails, but I can't believe it.
Stick to those beliefs mate, definitely not rocket rails. Not entirely sure what they are....test equip of some sort maybe?
