This is my broken one, with a Platinum cart for size comparison.
The metal connector was damaged during a repair attempt, the Platinum cart fits at the nipple but is too long for the oen, and now I can't find the working pen (which was coral and silver) of the pair I had.
My other pen is a Montblanc.

I've long tried to track down any information about a connection between Aurora and Platinum like the connect that existed between Aurora and Parker during the immediate postwar era. The search started when I discovered that the Platinum cartridges and converters fit in the old Aurora DuoCart fountain pens and the smaller almost International Standard length DuoCart cartridges (I have some empty ones) fit in my Platinum pens.
Modern Aurora cartridge pens (and early ST Dupont fountain pens) used the Parker standard cartridge nipple arrangement while the earliest Aurora cartridge pens use the much wider mouthed Platinum standard. The full length Platinum cartridges fit in the Aurora (older) DuoCart pens and I wondered if the DuoCart was simply a marketing gimmick or possibly a way to get around a Platinum patent.
So far though I've had no luck but the lack of any evidence of corporate cooperation agreements tends to point towards patent infringement issues as the more likely path.
The kind gentleman who gave me the pen just sent these cartridges (photo below). I've never seen such things. My first impression is the metal will damage the pen. Is what appears to be a steel ball bearing merely a thin foil layer designed to be pierced? Or am I supposed to remove the ball before placing the cartridge in the pen? Or...?

No, that's how the Plat carts come. If you're reluctant to ise force on the pen, I've pierced carts with a thumb tack (Gullors really need this technique.)

I think I better pull the cartridge I've been refilling that's in the pen and have a close look at what presses against that steel ball.
Yeah, Fred, Plats have those crazy balls that get punched in and become agitators to break up surface tension (?) so the ink doesn't stick to the side of the cart and keeps things mixed up. I agree: I can stand punching them into a pen and just poke it in with something else, or a really cheap Plat pen like a Preppy.

If you have anything like a really small-diameter wooden dowel, that works too. We have long cotton lab-type swabs on wooden sticks. Dual use!

I've never had any issues related to the ball stopper using platinum cartridges and that's over may decades of use.
Punching the plastic of a Lamy or Parker cartridge needs much more pressure and force than pushing the ball of a Platinum cartridge, so don't worry Fred.
Reminds me of this ...
