The Swiss National Archive has began to put online part of its documents. Some concern bombs and other ammunition and can be accessed using the various keywords - bombe, bomben, fliegerbombe, flegerbomnen, munition, munitions, munitionsfabrik, Thun - in the search portal of the archive:
https://www.recherche.bar.admin.ch/recherche/#/en/search/simple
Then on the results page chose your menu language (in the upper right corner DE FR IT EN) and in the Filters panel (left pane) choose " Documents available in digital form" "Yes"
The documents are filed according to the "aggregation principle" - inside a given period, all documents concerning a specific subject are regrouped in the same file without regard to their date First Problem - the cataog does not include the subjet of the files (though the cover of each file is also scanned) but an arbitrary number.
In practice you must open each document to look at what is inside
Second Problem - The site use the Open Access Matador Viewer for displaying teh content of each doument - a very good viewer but without an easy possibility of downloading (as all multi resolution viewers) . The easiest thing to do is expand teh screen to full screen and use a screen capture program to capture what you want.
Third problem - The documents are of course in German (a few are in French) - so if you want to translate an image copy of them you'll need either to master this language, or tio use an image to text converter - there is a very good one online at https://www.imagetotext.info/
Enjoy many hours of exploration....
Here're the drawings of bombs found there (most of material covered for the pre 1950 period currently only includes the 3.5kg, 6.5kg, 12kg bombs and the incendiaries) - but the text and tables throw a lot of light on the developping of all Swiss bombs, including for instane the details of the collaboration with Bofors in the 1930, or the reason why the 200kg bomb though planned already in the late 1930s was not produced till after ww2.
