Ingrandimento 1x e 2x rotante angolo retto senza marchio per Leica SL2 / SL2s

I believe these where custom manufactured in germany, but are marked japan. Not a whole lot of info online. I am not positive if this will mount on the SL2 as I only found 1 photo of it elsewhere. Is different from the one that mounts to the S / SL (Typ 601).
