Ok guys and gals, cats out of the bag! Will be making one long post with questions and of course, the photo dump. Since starting this project my original intent has been to make a beautiful G519 replica for the Warbirds Of Glory museum since no original bikes for restoration were around. I am proud to say I will not only be building the replica still but as well as restoring MG88243 / J9 using all the original G519 NOS parts I have collected from the great people off this forum. First off here are the pictures of the original G519 frame.
Now for the parts being used in the restoration! So far have collected the following:
NOS Rear G519 Fender
NOS Delta G519 Headlight
NOS G519 Handle Bars
NOS G519 Chain
NOS Set of blacked out Torrington #8 Pedals with original wooden inserts.
NOS in box Chain Guard (Will start a discussion about this later)
Kevin's reproduction hand grips
Coffin style Chainring
Columbia Truss rods and brackets with bolt
Columbia front fork (Stem will need to be shortened, but have questions below)
Rear reflector (Have questions below)
Crank (Have questions bellow)
Now for the questions that I need help with from the masters!!!!!
Question #1: I have two types of rear reflectors. Which one is correct for a 1942 G519. The LH or RH one?
Question #2: I have two appearance correct kickstands. Both differ on the stand itself with end length. Which would be more correct longer or shorter?
Question #3: How do you date these two cranks and which one has the correct bearing races and nuts:
First one has the markings A8 on one side an a J on the other:
Second One: This one has a 3R stamp on the bearing race and what appears to be OF on the crank.
Still with me? Question #4: The bearing race inserts that go into the frame. Which is correct, 4 to choose from?
Last Question for now: Stem bearing hardware. I have 3 types of upper bearing races as well as two types of nuts. Which do you believe is correct?

Notice the two nuts on the LH side have a lower nut profile

From top to bottom, Straight cut, Tapered to the LH side, Tapered to the RH Side.
Few.... that was a long post but thank you all again. If all goes will I should have an original set of wheels and tires coming to the restoration. Still need to get an original seat and seat frame.
