Need advice on this vintage Patek Philippe

Tony C.

If you find a "cheap" AP, PP, or V&C, the likelihood of there being good potential for profit on re-sale is very small. There is, with few exceptions, a good reason that they are cheap to begin with.

In order to play that game successfully, you need both knowledge and experience, and, as suggested above, it's not good form to simply ask more knowledgable collectors if you can realize a profit on a given watch.
