I have 2 FML Glock 17 ten round magazines. These came with an early Generation 3 gun and do not have the ambidextrous cut. The follower is marked 2183-1 and the baseplate 3206. They don't appear to have been used much at all, only thing I've noticed is the button to release the baseplate has some scratches (not the baseplate itself) like they used something sharp to push the button in. $35 shipped or trade for Glock 19 mags or a Glock 33 rd mag.
