A pre-war (or post-war) Terrier in .32 S&W Long would be quite valuable seeing as how the Terrier was a .38 S&W built on a .32 RB frame.
If what you have is in .32 Long, it's a .32 Hand Ejector of some sort, not a Terrier.
Post the serial and a picture or two, someone will be able to identify which .32 HE it is.
