You are on the right track. Looks to me to be A Gem 1912 or an Ever Ready 1912. The GEM is made in the USA and the Ever Ready in England. You will be able to tell by the engraving inside the head of the razor and on the rear of the razor head. I have an Ever Ready 1912 - the inside of the razor reads "Ever-Ready British Made" and the rear of the razor head reads "Made in England".
I am currently using my Ever Ready - see here https://paste-and-cut.com.au/community/threads/shave-of-the-day-thread-2018.4560/page-30#post-117887
They are great razors - the blades are very rigid, hence no blade chatter. You need to shave with a relatively shallow angle i.e. blade almost parallel with skin. I'd rate it as mid-aggressive, but certainly nothing to be afraid of. I am really enjoying it.
