I have just inherited a large number of Dominion and DC Co company doc’s, notes and a history of major events *by John A Belton). I have summarized the key information into a chronological list from 1885 to 1945. It is about 8-9 pages long so too long to post here. It includes key names of people, start and discontinue date of brands of shotshells, calibers, new processes, patents etc. If there is any interest in this, I can publish on my website and include a link to access it. Let me know via email or on the forum if this is of interest to anyone and I will make it happen. Thanks.
OK Guys I have it up on the website.
You can go to my mainpage: www.cartridge-corner.com and then click on the headstamp page and then at the bottom right a link to DC CO info.
Or a quick link right to the page: (just cut and paste in your browser)
