Following the excellent example of Ron Merchant and Roger Hugel, I have posted the following material on my website under the Free Downloads button.
DWM: 3 Catalogs and 4 Ballistics Tables and a copy of the 1913 case index
Geco: 4 Catalogs
RWS: 8 Catalogs (one a B&W copy).
I made/received copies of these catalogs 4 or more years ago. They are not perfect but they are readable and have lots of info.
If anyone has other copies they would like to donate to this effort, please send me copies (ideally .pdf) and I will put them up on the site for all.
If you have a question drop me an email or a PM.
