Whelen Products Release Dates

[MCGD48]

Is there a place or a file that i can see the release date of every whelen product ? I already consult the whelen history page on their website, but there's plenty of products that are not cited.

I'm looking if possible to get all the products since the debut of Whelen.

Thanks in advance.

I can help with many of the vintage Rota-Beam products.
