CASE: didn't look too bad before, but looks a lot better now. welcome to the forum and looks like you need another bolt in the base and you are good to go for about 50 years with a little maintenance.
might i suggest that if you cut or file or saw anything in your Wilton to maybe throw down a clean or even a little oily rag on the slide to keep the debris and junk from going on the slide and eventually inside your vise so you won't have to clean it as often.
shaking a rag off or throwing it away (even paper towels work too) is a lot easier than having to clean and grease your vise more often and a lot easier on your vise.
