So how did you find all of that? You don't find those in your local junk shop.
It has taken an extreme amount of patience and perseverance in some cases. A couple pieces took a few years of poking at the people who owned them saying "hey I want that, don't forget I want it" and sending them photos of my collection so they knew I was serious. Others were lucky finds searching on craigslist and other online sales/auctions/etc.
For example, the New Tech Lightstorm that I recently sold (since I didn't need two) I had originally found at an antique store in North Carolina. They had a facebook page and posted photo overviews of their shop and I saw it in the photo. Called and asked if they still had it, arranged payment and shipping and it was mine.
I like your collection of speaker/lights. It looks like you've got all the major brands and models.
Thank you. There are a couple I would still like to find someday (Whelen 88 PA, Dietz's early light speaker combo, and the Whelen "vader light").
