Well, new to me anyway. It is a vintage Smiths Empire which has been fully rebuilt, ultrasonically cleaned and properly oiled or so the advert said. Anyway the detailed, supersized pictures convinced me. I've decided to make a leather strap for it so that it can loop onto my belt then hang it securely in my trouser/pants pocket. I'll make the strap removable so I can attach an Albert chain or similar for wearing with a waistcoat. Thanks for looking folks!
