Just wanted to bump this thread to say that I finally decided to order a couple of these (one for my standing work desk and one for my IBM 5150). I found the store Shoplet.com had by far the best price.
https://www.shoplet.com/Innovera-Standard-Des … r/IVR53001/spdv
$23.10 each with free shipping and no tax in my state. Two of them for $46.20 seems really good. Saves me $18 versus amazon. 😀
Also, another site has the full measurements listed as 22" x 15.59" x 3.54" , with a keyboard tray pull length of 15".
This is big enough that I actually intend to use one for holding a mid-size tower laying down on my work table so I have a place for the keyboard when I'm testing components (I prefer to test cards in this orientation so I don't have to keep putting screws in).
When I get them I'll try to remember to post pics here. 😀
Now for some blitting from the back buffer.
