Estes Solar Launch Controller #FS-10 Part 2

Here's the controller, right out of the box.

The micro clips are clean, never used.
The interlock key is there!
Even the black name sticker was set on straight.

From the 1972 catalog, here's the prototype, pre-production picture.
The profile shape is the same, but in the finished product - 
The safety key doesn't have the black molded end.
The launch button is gray and surrounded by the decal.
Below the launch button is a ridged panel, not the three raised blocks.

From the side - 
I like how the upper end is raised up to easily see the key, light and button.

Opened up - 
There is a piece of paper taped into the inside showing battery directions.
Usually the positive and negative battery positions would be molded into the plastic case.
Whoever assembled the unit felt it necessary to add this. Well, we've all put in batteries incorrectly and wondered why things didn't work.

There is no battery acid discoloration on the contacts. This controller was never used!
