Help what are those?

I got a few parts from a old fellow who was working in the CDN forces long ago (weapons tech). Those are mint, new old stock. I was only able to grab 3 sights and 2 or 3 of those sniper swivels (I dont know the correct name for those). The sights are LB marked for LongBranch, the swivel appear unmarked and are fitting perfectly well on a NO4 MK1. There no rust at all on the parts (cosmoline only) those have never been mounted. Can anyone help me first by identifying those? One of the micrometer sights got the marking CR/C2.
All are LB marked, Cbroad arrow marked... If I put these parts for sale, what would be a good pricing approx? Cant see those parts on Ebay...

thanks for your help guysAttachment 27144Attachment 27145Attachment 27146Attachment 27147Attachment 27148

the first sight is a standard No.4 rear sight. The next two LOOK like some sigths I saw a couple of years back whihc may require drilling and tapping of the receiver to fit to the No.4 or No.7 rifle (I suspect No.7 as range is marked 20 and then 100, presumably yards). The last two pics are Target / sniper swivels for the Main screw in fornt of teh magazine (probably for the NO.4 or No.7 again), the name of which I don't know exactly correctly so will defer to someone else, though some call it a king screw,

The second and third pics are the sight for the C#7 rifle in .22 cal. They mount instead of the one in the first pic. Same way.

Just research the sling loop carefully before you advertise it. Coming from an RCEME Armourer it is PROBABLY off a No4T or a No8 but it COULD be a longer commercial Parker-Hale type that isn't genuine. You can't tell from the photo. The REAL experts will try to convince you that they're the same until they're blue in the face............ but guess what?

Hello Peter, thanks for the inputs. Giving the origin of the parts I'm pretty sure they're not civilian copies but I researched them nevertheless. They're no Parker Hale for sure, no markings and has the correct "short shank" screw. I tried one on my NO4 and it fits prefectly. I'll check them out a bit more online.

thanks

They both FIT but but the sniper swivel will not rotate through 360 degrees, being stopped by the little loop. The commercial one will rotate fully

Its doesnt rotate fully because of the little loop, and got the right "short shank" screw

I found (to my cost) that the SMLE sling swivel does not fit the No. 4 thread. The maker´s stamp should (might) be on the head.

The first sight would be of interest to someone restoring their 1941 Long Branch No4Mk1 (NO Star)
As noted the second one is for a CNo7Mk1 .22 RF trainer. They aren’t overly rare around here and not terribly practical for someone looking for a windage adjustable sight for their 303 due to the mods needed to install them coupled with the limited elevation adjustment. The little windage lead screw is a nice find as these are somewhat delicate and can be bent giving less than reliable adjustments.
Given the sorce and 22 trainer sight I’d bet the sling loop is also for a CNo7 trainer.
