Looking for Technical docs on Douglas B19 and B23

[The Stannum Liberator]

I'm looking if anyone on here happens to have anything about these two, because actual primary data, and reports and such are very difficult to come across, (I'm planning on visiting DC in a few years, but thought maybe some of you have something)

Any help would be appreciated

This is the only thing official I have:

"Wayback Machine"

I did run across a different partial report a number of years ago but it was a transcribed report and not downloadable. The website also had a lot of photos including the interior, but it seems to have disappeared.

Otherwise, the Inch High Guy has some nice photos on his website:

"XB-19 – Inch High Guy"
