aperture without drawing number and without tracks

[RCS]

Got this from "Mac" years ago, he said there were not many around that were still left in the system

Robert, I'd have to agree. I took me awhile to finally aquire mine. But at the same time I'm almost positive that there are many out there being passed around as wra no tracks.

Robert, GTforme,
Were do the narrow track apertures fit in? Here is an aperture without number and tracks, narrow tracks (I think), and normal. I think GT4me is probably right, as I recently purchased a GT unnumbered rear sight base with the concentric circle as a common wra base.

Can someone post a photo of a Springfield no-track aperture as compared to a WRA aperture, please?

[CCyooper]

Here you go, SA on left and WRA on top in profile picture. I hope this helps

Thanks CCyooper!!! That helps a ton!!!

Time to go check my stash......... b1

After checking my stash, it appears that I have three no-track WRAs and one no-track SA. Good enough for me!! Thanks again CCyooper for the comparison pic!!

Brian, that profile difference exists all the way through WRA production as far as I know. Good trick to know.

Would this be the correct base to use with a no-track SA aperture?

Billy Pyle's data sheets on gas trap rifles show the early rear sight base without the drawing number around 30K serial range. What serial range are you going to use it on ?

The early rear sight base without the drawing number was also used on the early Winchester Education Order rifles too. Far right rear sight base was also used on the early Winchester rifles (note the color)

Thank you for the info, Robert.

I have stripped receiver 30860. It has the 7th-round correction, but is not annealed. Perhaps I'll do an early war rebuild with this one. I have so many projects in the works right now that it's just going to have to wait for a while, though.

So whats a SA without tracks go for nowdays?

Seem to run from $45 to $75 each depending on condition etc...

Also, if you have any early bases without the numbers, but with the extra milling cut please let me know. I could use a couple more.

Looks like I have another one of these on the way!!

Thanks to a special friend

Just going thru some old posts and realized I didn’t see an answer regarding the use of SA narrow tracked apertures. Does anyone have a serial number range for their use? I expect it was a short duration.

Curt, A few serial numbers for possible reference: s/n 28616 aperture unmarked thin or narrow tracks, s/n 34919 aperture no tracks s/n 42664 has tracks
