Link not flush with frame|Restoration, Repair and Maintenance|Forum|Winchester Collector

I am looking at a 1952 Model 94 and noticed the link protrudes about 3/32” and is not flush with the frame when the lever is closed. Is this normal? What could cause this? I have a 1940, 1951 and 1956 model 94’s, all of these the link is flush with the frame. The sides of the hammer are also a plume color which makes me think someone has reblued/replaced the hammer. Any thoughts?
