I thought HP White Labs was in Maryland, and has been for quite a long time. About 20+ years ago the lab began selling their paperwork and collection. Bill Woodin bought quite a bit of it including their collection of seperate bullets, because he thought the DWM duplex bullet illustrated in one of their books (as I recall) would be in the collection. It wasn’t there, and there was nothing else Bill wanted so he passed a portion of the collection on to me.
The Lab also had racks filled with files they had put together over the years, and I was told there were quite a few old cartridge catalogs in them. The boxes were being auctioned so I bought one that I thought likely to contain a number of cartridge catalogs. It has some very interesting old gun info, but the only cartridge info was an old Xerox copy of an early German catalog. I knew an ex-Agency guy who had a lot of dealings with the Lab and asked him about the files. he laughed and told me not to waste my time on the files looking for cartridge catalogs. Over the years he had gone through them all-with the Labs permission and pulled out the cartridge information and sent it to Herb Woodend, which explains the stamps on many of Herb’s catalogs. I still have the White Labs box in my storeroom.
Still, a large amount of things were sold off/given away. I understand none of the collection, or at least the old collection, remains. As far as I know it was all owned by the Lab, at least they disposed of it as if it was owned by the Lab, and none of it was government owned. Various government agencies apparently hired the Lab to do quite a bit of work for them.
I know some of the earlier generation of collectors knew the people in the Lab and visited it. I never had an opportunity to actually go to the Lab so l what I know is basically second hand.
