its a 50-50 proposition here, at any time buying a vintage razor.
looking "rough" can simply be the result of sitting in a closet for 50 years after being put away wet and soapy.
looking rough can also be a sign that the razor has mechanical issues, however lots of folks get vintage razors with bad finish that turn out to be "near factory new" on the internal, mechanical end.
The finish appearance is secondary to how the razor itself is, gaps in the doors, bent looking doors or safety bar, a piece missing, a handle that's 30-45 degrees off being perpendicular to the head... those sorts of things one MUST look at.
Replated razors are not necessarily evil, but one should put a tad bit more look at physical damage and defects. A lot of the companies doing replating jobs on razors are companies that make their living on say, custom replating of trailer ball hitches and bumpers. the finish wont be done to razor standards, thickness mainly. and pre plate prep wont be what it should.
A lot of razors will be damaged during the replate process, there is a place called razor emporioum that has mangled countless razors for charge.
that is based on customer service emails put onto forum complaint threads on that company. The best classic is about a fellow who had sent them a fatboy to replate and clean. after 6 months of waiting, he contacted them and was told they were waiting for him to send THEM a replacement tto knob and spring because they had broken the one on his razor during tear down.
