I started a thread a few days ago on this subject. I have a straight stocked 2E engraved just like yours with no ducks and no oval. I hadn't ever seen one like it in ten years of collecting but there are plenty of guys on the site that have them as well. SGT posted some great info in my thread about why some guns have ovals and some don't. If you haven't read my LC 2E thread yet you might find it interesting.
