Thread: any suggestions

I won this one off eBay . Sheffield brand with what appears to be bone scales. I know I've go some time coming with the sand paper to remove the rust that's showing but how about the scales. They have what appears to be rust inside and kind of duel looking out side. I wonder if Polident over night will clean them up as it does teeth or should I use something else. any suggestions.

Also I've seen the brand name before but never used one. anyone use one of these razors and what do you think.
