I never seen a pre first war or twenties auto-5 with rib. I have a first month superposed production (1931) with a vent rib. That is the earliest Browning with a rib I ever seen.
Marc here is the link to it. However it’s a 39 not a 38. The pictures don’t show it but the barrel has a matching serial number. Maybe the rib was added? http://browningowners.com/forum/index.php?threads/1939-sweet.11243/
I really really don't like you now! Very nice collection and I'm envious. I don't have near that many beautiful guns but I'm slowly working on it. Maybe someday. Sent from my LG-H700 using Tapatalk
