this is not the 50-110 Win Express but the honourable 12,7x60R 500 BPE
like the name is telling you made by cuting the 500 BPE case to 60 mm. there was a 65 mm long version too in germany and austria, done because the 76mm /3 " case was to powerfull for common european game.

late turned NDFS 50-110 brass, two original 12,7x60R cartridges by RWS and Roth, 500 BPE coiled case

I had to made once ammo for a belgian SXS combination gun in 12ga and "12,7x60R". after making a chamber cast I found it was the american 50-110 Winchester, no doubt about it. this was the time when only the late turned NDFS brass was available.
