I've noticed an increasing number of shelf queen piccies with period electronics and batteries fitted. Although I don't have the patience for this kind of thing normally, I can see why collectors do it - it add's that extra something, makes the cars look ultra-authentic.
My geek-side wants to try this with 2 of my shelf queens, but I'd like to know when the battery types came out. I did a search and found the "Battery Timeline question" thread (locked) but it doesn't seem to have what I want. Has this been done before? I know the search function is poor so I might have missed something.
It goes like this. I post this picture, and hopefully some nice knowledgeable people can tell me roughly when the batteries were on sale.....?
