fallschirmaeger,
Last year I bought a Krieghoff 16x16-7x65R from them, that had been modified for an EL. I just happened to have a Krieghoff EL in 22 LR, and it fit right in, it even had a decent start on regulation. So, there is a decent chance yours may also be set up. If not, filing the notch in the extractor isn't that hard, but getting a flat area in the rim recess( to fit headspace screw) without the tool might be a "trick". BTW, 7x57R is one of my favorites.
