Reproduction scope and mount are not in alignment with the barrel bore
I put the reproduction scope and SARCO reproduction mount on a naked L42 that has been setting on the rack looking funny without a telescopic sight for the last fifteen years.
The scope went into the mount with no difficulty and buttoned up with no problem. I put it on the rifle and set up a Busnell Collimator to evaluate the sight vs. barrel correlation.
I was able to confirm what Peter has said many times in the past. The scope/mount was not in alignment with the bore. The sight picture is off set to the left further the scopes' ability to shift the pointer into alignment.
I will try a few other mounts and naked rifles to see if I can find a combination that works.

Has anyone taken the time to compare the dimentions of the repro pads & mounts to those of the orininals? If it's the norm for the sight picture to be offset to the left then maybe the makers of the repro stuff might be a bit smarter than they are being credit for. If the scope fits the mount and the mount fits the rifle then it sounds like they left some extra meat on the pad/mount mating surfaces to allow the purchaser to precisely fit it to a particular rifle. Especially if it is being installed on an original thats missing just the mount.

The front spigot on the SARCO can be to shallow. I have a photo of one that is .060" and another that ran .080" that's 8" at 100 yards right,, I must have that wrong. .008"=1" at 100 yards I think. Well they are way off but fixable. I should write this stuff on the back of my hand. Plus the back of the bracket is also fat so maybe it's that way so you can fit it like a 91/30 Mosin bracket. Better to be to fat than having to shim.
MJ, don't take this personally, but that's crap.

When you see them side by side the Sarco is way different to the original in quite a few ways.
There is clearly a lot of variance with the Sarco mounts. Mine looks a lot deeper.

I agree there Oxford Andy and good advice. If you have an original but bracketless No4T rifle, then that's the only way to go. It might take a bit of hand fitting to get it all exactly aligned but that's what we had to do anyway, even when we were forced to replace a bracket with an original part worn/used one.
BUT, the repros from Sarco and the now repro scopes give everyone a chance to make a repro No4 sniper. And so long as you follow the previous instructions you've got a lot of leeway. And if you don't drill anything until you KNOW it's dead right (remember the old phrase, measure twice, cut once.....), you can always go back and start again

miss alignment of the datum and drum seems consistent with all of the scopes seen. The clicker plate turret indexing is not correct and there is also no aligning pin between the range drum and the clicker plate. Also, the profile of the plunger is not good and will either wear into the clicker plate or more than likely break off at the head from repeated use. I've had to "tart up" the ones I've seen so far.

I am assuming since they are no longer listed on the Numrich website, they must be sold out.
