That pic below is a bad example of what I was picturing you saying. Totally agree on the older machine opinion. And it's always been my opinion that one day we won't be able to tell, when they get the pattern right.
Dean or Norwich phrased rainbow milling to me.

I'm not winning this one am I?

Redfield seemed to have a better finished leaf than what's on a Square S. Was the Lyman the maker of the serif S base?

If it were loose,I'd have bought that sight on the Quality several times over before this thread and felt proud of the buy I made.

@ Logman, Hi and welcome to the forum from New Mexico!

Thank you for your inquiry. Thanks to you and the others that have contributed I have four more excellent examples of flip sights to add to my photo library.

The more I think I know about carbines, the more I realize I have lots to learn.

Thanks for the free education.

You can see the milling on the side where it was later worked down for better finish, not that unlike Logan's pics. Additionally, Logan's sight was mentioned as being not straight, but that's just one side. The other side is flat/straight. The bowed side is from installing on a tight dovetail.
I wonder what the bottom looks like on your sight, Charlie?

Years ago I would knock it out and take the flip apart......... But Welby/WTMR threatened to cut my fingers off.
I'd 'Presume' mine would have that Smooth Small Circular Mottled Orange peel looking milling on the bottom, like most SQ S sight bases I've seen have. But I've also seen them with just fine milling marks. Though none like the heavy milling marks seen pictured here on the bottom of this round S base that has .U. stamped inside it.

IDK, it may be something as simple as how new and sharp or worn the milling bit happens to be at the time or the style of the person working/making it.
It was all about removing metal to get to specs.





Speaking of INSIDE MILLING, The Inland base below was taken apart to replace a limp
 nearly rusted in half spring.
Looks as though the Milling runs side to side when compared to the .U. base above.
Different methods ?



As far as a side or corner of a base being bent in, it could be a simple matter of tapping the wrong area looking for a Windage correction. It doesn't take much force to do so. I had one bent in that wouldn't allow the flip to fold over. Ended up threading a nut on a hex head bolt that would just fit inside. With the base in a padded vice (to keep the other side from pushing outward) I backed the nut out until it had the side squared away. Nervous while doing so ?.....  YES.
I stashed that little nut/bolt combo away in a parts tray.

Cheers FWIW,
Charlie-Painter777

Charlie. Those sideways marks I believe are chatter.

No way of that I know could machine side to side like that and leave a flat side wall.

Yes. They made staggering cutters much like a table saw blade to reduce chatter. The cutter that did that has only perpendicular teeth

Yeah, his sight was not made with a bent bottom. It was forced into the shape on install. This camera is poor for close ups but this is the bottom of Logan's sight. Notice any resemblance?

The heavily bent side is the non-S marked, the right side which leads a person to understand it was probably installed the wrong way the first time it was installed.

Also, watch the rear crater for location. Here's Logan's receiver with the serif S slipped on by hand to stop, then two well used Square S flips installed. And look at the big bur on the rear edge. It's no wonder the sight is bent.

Dovetail looks filed open. Taper larger on left.

Oo, good eye. You know what, that dragged off Parkerizing on the left side might indicate direction of install (or removal) at one time, huh?
With the Harbor Freight calipers measuring inside the craters on each side the dove tail is exactly the same width. So there is no taper at all, which could also explain the bent sight?

After going over this sight for a few days, acquiring a better camera for comparison of minute traits with other flip sights (side by side), measuring all aspects of the sight against known obvious USGI sights and comparing milling, there is nothing about the machining and sizing that says it's not a USGI sight. Because it is USGI. All these steps were interesting because I've never had to do this to determine one in the past. It was interesting but needless.
If anyone has anymore of these sights for sale please contact me because I'll be happy to buy it from you.

10,
Have you ever compared Flip sights by weighing them ?
