How do I know it's really TRW?

Hey Everybody,

I just ordered a complete rear sight assembly advertised as TRW. I was wondering where I need to look to find the TRW markings, if there are any. I haven't disassembled it to look but don't see any visible markings on the exterior. Any idea if this is the real deal or not?

IIRC, TRW made some rear sight bases but sub'd out the rest of the sight. I've never seen a base marked with TRW or a triangle, so I dunno how you'd tell.

Thanks from Potus2000

Trw did make the sight base but it was not stamped, the windage knob will be marked Wright and the elevation knob will be wce w/ m for meters. There is really no way of knowing for sure if it is made by TRW, just if it is correct for TRW.

Do a search markings for TRW rear sight.

Good Luck,
Ren

Thanks from Potus2000

If I remember correctly DRC windage knob is also correct as well as others. Different has a list out there somewhere, I think on the EBR forum-I have it printed out at home--not at home now.

That is correct DCR made windage knobs and NHC made elevation knobs for TRW. TRW made their own sight bases but they were not marked in any way. There is a way to tell if it is a TRW or not. Until I get one I'll keep that to my self.

Tease! So I may or may not have a TRW base but my knobs are legit.

It's your girl, if her knobs are legit the rest of her is most likely ok

In the real world it's unlikely the initials on the knobs or some kind of mark on the base would have stayed together after the original TRW M14 rifle made a couple of stops at a maintenance depot.

Keep in mind that all GI parts were made to the same specifications. The only significant difference in any of the TRW parts was in the operating rod which was produced from a one piece forging rather than having the tube welded to the handle as was the case with all other government rifles. That isn't to say that the others were inferior. In fact they all held up quite well and failures were few. M1 Garand operating rods were also welded together.

TRW sight bases were indistinguishable from all the others with the exception of Winchester bases which were marked OM, and probably subcontracted, as well as Harrington & Richardson which were also marked. Some late contract National Match sight bases were marked with the manufacturers cage codes and some of those were marked with white ink that usually rubbed off after a little use.

My best advise is to not worry about who made the rear sight base. There is no way to confirm it was TRW.

Thanks from JD Russell and usmce8s

This is so untrue.

Dog fight... what dog fight?
I don't expect everyone to agree with my personal opinions and I'm sure I am not always right all the time. I'm sure Ren will tell me what he disagrees with. If I feel he makes a good point I may change my thoughts on the subject.

I am aware, by the way, that TRW rear sight bases do have an identifying feature. I can't remember exactly what it is, but I seem to recall it has something to do with the outside contour of the rear bottom edge where it meets the ears of the base.
