Richard Hibbs-Western Cartridge

I have a collection of his company work books (1928-1946 & 2 from the 1960’s) It appears that he was a production engineer ??

Details that I have gathered by skimming them include details of cartridge production from bullet shapes, alloys & loadings of certain cartridges & shotshells.

If anyone can give me any info about him to put these books into context, it would be greatly appreciated.

If anyone has any questions about Western cartridges from this period, feel free to ask,it may be here in these books.
