BHeck: i would guess the same as Greg mentioned that your old Parker was probably black originally. you might want to check out posts 117-124 on the Vise Repair 101 thread to see how McB restored his old Parker. Please add pictures and a couple posts of yours on that thread so it won't get lost like so many other good restorations.
also welcome to the Forum and hope you stick around to learn a little and teach us what you know. i know i can honestly say i learn something or a few things almost every day i read these posts or ask a few questions and get the guys that know what the answers are.
any pictures of your Parker to post on this thread or post over on the vise repair 101 thread and it might get seen more?
