Mike, I presume you know what the word "Umarex" designates. I have owned the Ulm/Manurhin .22, and certainly would not confuse the two. Mags for the Umarex are also hard to find locally or on line. Just trying to do a favor for us plinkers.
As an update I can report that I ordered 3 of these from Earl on Sunday evening and received them today. All three are exactly same as the one original in every way. Very prompt service and yes, $19 each. Good deal and nice mags for the Umarex .22lr
