Here's a place to see what stuff looked like when you could buy it off the counter at your friendly local Willys Parts dealer.
If any of y'all have NOS stuff and want to share the pics, please do.
I'll start with some ALA tail lights I recently lucked onto. And NO, I did not pay the $6 a light marked on the boxes..I can only wish. They are not for sale but I would trade one for a right side lamp in similar condition. Here's the box:


The green arrows point at the cast in holes for vertical stud mounting of the light on an earlier jeep. In the parts book I have this is the only light listed for ALL the universal jeeps, even though we know it was not an original light on most 2A models.
(Used on some 48 2A jeeps, if I am correct..) Use started with the serial number 53678 1950 3A, see Bob W's post below.

This shows the sticker that told the end user to change the bulb if used in a 12 volt jeep. And here's the tail light from the top, you can see the ALA marking here.It is so you could read it when the light is on the jeep.

I have some more pics and will add them soon. Photobucket is being a royal pain. I miss the old Webshots.
