What effect does having matching vs non-matching numbers on C&R rifles have? Does it affect accuracy?
Importance of matching numbers in C&R rifles

Nope, not as a rule, it only adds monetary and historical value with all matching numbers. An unmatched rifle could conceivably be more accurate than a matched one.

What he said, it can make a very significant difference in price, double, triple or more. Of should I say, non-matching guns are often worth 50% or less of the value of an all matching gun.
And some won't buy a non-matching gun for any price.

Matching numbers are always desirable. Rifles such as the K-31
Schmidt-Rubin usually have matching numbers. Some of the mauser
rifles from south america have mis-matched bolts. This was rumored
to be due to bolts stored separately from the rifles. Any weapon from
the turd world is more likely to be mis-matched.

rifles were hand fitted and numbered during assembly because of less accurate machining.
if all the numbers match, the original tolerences are retained

Matching numbers means nothing for accuracy. Doesn't guarantee good headspace on any rifle either. Some rifles, like M1 Rifles, should not have S/N matching numbers on the parts either. If an M1's part numbers match the S/N, somebody made it that way and it drops the value.
"...rifles were hand fitted and numbered during assembly..." Um, no. Military rifles haven't been hand fitted for eons.
"...the original tolerances are retained..." Nonsense.

Sunray, you sound argumentative so.... he was speaking of rifles made "eons" ago, and both the Swiss and Swedes were quite fastitious about numbering each part of a new rifle to it's serial number.
The odds of having a correctly headspaced rifle do rise if it's parts are numbered to it and it is not well worn. This is not to say that a mismatched rifle WILL have incorrect headspacing but if the mismatch is the result of haphazard storage or unit handling of weapons it very well could mean that. The classic example of drill sargeants making recruits disassemble their rifles and put all parts on a blanket in the center of a troop bay then turning off the lights and giving all of them 30 seconds to reassemble an operational weapon could very well result in a slighly shorter bolt ending up in a slightly long chambered rifle Even though the differences between parts might amount to only a few thousandths of an inch, tolerance stacking could result in a no-go condition or a failure of field type headspace guaging.
"One size fits all" manufacturing techniques were not developed to a useful point until American factories did it during WW2. Most of the milsurp equipment being discussed is of WW1 vintages.

thank you krs...that's what i thought we were discussing, rifles that were fitted and numbered accordingly
