I wrote that article YEARS ago, back in 2015. I thought I had cited it back then, but maybe not. I still had a bookmarked list of sources I used to make the article, here they are: https://news.google.com/newspapers?nid=191&dat=19790826&id=nRNMAAAAIBAJ&sjid=tkQDAAAAIBAJ&pg=6834,36525...

Is this one of the older 'horizontal aspect ratio' timers? There's some information here, but sometimes the photos don't load:
