Old hybrid

Hello M Frame friends , question for ya,
I got this lens cheap, but it will not fit in my “new” or pro M’s,
Was there a size difference between the very first Mumbos and gen1/new M/ Pros ?
All i know is that this one is shorter from hook to hook and has no etched Oakley on the lens compared to the rest of my lenses .
Help please lol

Ya the 1st and second gen m frames are more narrow lenses, they typically fit super loose in a new m frsme and pro m frames, sometimes you can get lucky and ur stays in
