Hi Drew, Here's a Field Grade that just had all of its metal restored that has the angled bottom junctures. The crazy thing is that it has all of the original parts (except the stock) and serial number FWE128918 which makes it a 1930 gun! I fit an original Smith stock from Jerry Andrews and examined the frame carefully while doing so since I found it strange at the time that such a late gun had the angles. However, there is no sign that the frame metal was changed from the way it left the factory. Never say never, right?
