My 2.7M has just a partial bomb - no flame there at all, but what's there is bright and through the parkerizing. An adjustable rear sight has been added, but doesn't have any stake marks where your picture shows them. Will try to add a couple pictures later. - Bob
Here's a picture of the receiver "bomb" on my Underwood.
Not sure when they stopped using the point staking for flip sights, but I really didn't expect them in the first place. This one is really early.
Punch staking on flips was done two different ways. This picture shows one way. The other way was with the point right on the line between the side of the rear sight and the lip of the groove. It usually made a divot in both the edge of the groove and the side of the sight. In either case punch staking was fairly uncommon with flip sights.
From what I have read Underwood was the only manufacturer to mark recievers with the flaming bomb.
The hammer bounce on the bomb strike is almost as heavy as the initial blow. The Carbine didn't appear used other than a handful of shots fired. The only story was that it came from a neighbor friend who inherited it from his veteran father brought from his service time.
My 28400xx rear sight is staked just like tenOC's, along with the double stamped flaming bomb, just not as deeply.
Got a pic you can share?
These are the only two I have on hand.
Looks pretty crisp as well. What's the barrel date? This one is marked 1-43.
