N Frame ejector rod shroud shape

[mod57]

Since I, of late, have a lot of time on my hands I have started to notice the different ways that the N frame ejector shrouds are machined. Some are noticeably rounded on the leading edge, while others are sharp. Some have appear to have a milled area on the right side, while others do not. Is there any method to this. I thought it was a time related thing but I have seen this across on old pre war guns as well as some '60s models. Barrel length
related maybe? Anyone got the scoop?
Thanks,

Well after surfing through many of the fine quality photos on this forum I think I have an answer to this. Seems like all of the rounded type shrouds appear on pre war/pre model guns (with the exception of the awesome Triple Lock).
Rubiranch's very nice 1978 HP shows the sharp profile and the longer milled area.
boatme99's 1956 HP clearly shows the rounded profile.
bdGreen's Superb Triple Lock shows a somewhat sharper profile but not as rounded as later guns.

I have also noticed that on the rounded types, the locking lug protrudes from the front of the shroud.

probably the same situation as the ampersand, different styles used over time, no real rhyme nor reason......it just is

27s

I never was aware of this detail: however confronting my pre-27 3 1/2" and a newer 27-5 6" , a little difference is present

I have noticed the varying shape of model marked n-frame barrels with the ejector rod shroud over the years. I my opinion, the older the gun, the more rounded the shroud is at its forwardmost point. I am sure there are exceptions to this, but that has been my observation.

Well, diecidecimi's 3 1/2" pre-27 has yet another shape. The straight cut I'll call it. All of this being said, I have to say that I prefer the later Model guns form the best. I like the sharp curved look of them, reminds me of a battleship's bow.
Thanks fellas, just another piece of minutiae of the hobby we love.

All I can add is some photographs. Here are three N frames from three different eras. Top, a postwar 38 HD, center a Model 25-2 and bottom is a Model 22-4 I also posted individual close ups.

Actually, on the 38HD and the Model 25-2, there is some sculpting at end of the shroud that is missing on the Model 22-4. I just looked at my 625-6, ACP Mountain Gun and the sculpting is absent there also.
