The bottom for sure.
The top one is 'probably'. Usually a company puts their own name on mags. or there isn't one at all.

OK People. Enough of this idle chit-chat.

Back to your oars. The Captain wants to waterski.
That's what I was thinking, based on some other reading I've done it looks like the top one is probably a military surplus magazine. The funny thing is the top style I have bought from my LGS for $10 because he thinks they are some off brand imported junk. But if it has the rampant pony on it he wants $45! I think that's more than Colt charges new. I know of at least 3 local gun shops that were taking one magazine out of the Colt box, and selling them separate for $30-$35 years ago. Word got around and their distributors told them no more or they wouldn't get any more pistols. I don't know how true it is but I heard that at one time this got to be such a problem that Colt only shipped pistols with 1 magazine. I've never opened a new Colt box that I can recall to see if they come with 1 or 2 magazines.
just checked all 9 of my U.S. issue ones, none of the WWI or WWII have markings on base - the post war ones are marked with the national stock number - i have several like top one in picture + iirc they are aftermarket -

My GI ones were either unmarked or had the stock numbers on them. I had a few with the lanyard ring as well, unmarked. The only Colt marked mags were from my Dad's 1911 commercial pistol and my FIL's NM pistol.
There are a lot of fake mags with the stock number on the bottom, the feed lips on the fakes don’t last long. I’ve used them for range mags, have also thrown some away. Someone sold then as ww2 surplus new on wrappers in the 1980s or 90s and since most folks fondle their guns more than shoot them they haven’t all broken yet.
The bottom magazine with the Colt Pony and the M. Is a Colt Factory supplied magazine made by Metalform. They are well made magazines.

Pictures of the top mag will help.
Metalform was mentioned on one, they're a good mag. Many outside vendors made mags for Colt and others that were factory mags.
jmho - mags pictured in post # 9 are definitely not Colt or GI, common aftermarket - feed lips, arched + dimpled follower - Sarco + others are currently selling them with floor plate marked like yours - have you function tested them ? -

Colt has not made magazines in a very long time. As noted, the one has a "M" which is put on "Colt" magazines made by Metalform. The other maker Colt is supposed to have making them magazines is Checkmate, and for theirs look for a small "C" stamped on it somewhere.
The arched, dimpled follower does not look anything like a "Colt" magazine, made by anyone.
You are blessed to still have your Grandfather. Both of mine died before I was born, one in 1940 and the other in 1955.
As long as they work, who cares?
I will agree that the magazine shown in post #9 is not a GI mag:; all the ones I ever saw had flat followers, whether they had the NSN on them or not.

I think metalform made the arched follower, not 100% sure. More sure that it was not purchased by US mil.
It looks like a metalform made mag to me. Not GI, but I think it's a real colt mag.
