Simson tool?

Ron, I'd be interested if it's a fake. I just want one that's functional since all I own is shooters, and all the repros currently out there seem not to have the offset cut that establishes the "hook" within the hole.

I bought a couple on eBay that looked OK, but what looked like the "hook" part in the pics turned out to be the result of drilling the hole with a bit ground off-center--a bit thus sharpened drills a slightly oversize hole until the very bottom, where it cuts through at the actual diameter of the bit. This leaves a beveled lip around the inside bottom of the hole, and the lip slips off the follower button rather than staying hooked over. The maker did not even remove the burr on the backside, and this could scratch the mag body if used this way. (I'd eagerly have traded actual functionality for the fake proof mark on it!)
I complained to the seller and they refunded everything, and I still have the tools, one of which now has a functional lip thanks to me and my Dremel.
