Re:
So the number 024453 places the frame as a c. 1980. This definitely narrows the model search. See Dave Scrimshaw's more recent numbers thread:

The apparent absence of a FD cable guide or stop suggests it was a 5 speed which would point to Cresta. Does it indeed have no FD cable guide/stop?
Water bottle braze-ons and yellow enamel (if original paint) point to a Coureur as you suggest and is described and pictured in catalog. However, at least in 81 catalog, Coureur is advertised as a 12 speed. Coureur came and went over the years and looks like only present in this iteration for 1981 and as no catalog available and serial predicts maybe 1980 as well. (It appears both Cresta and Coureur had same simpler Prugnat lugs, were plain gauge tubing and were most "competitively priced".)
See Kilgariff and catalog pic below. Also maybe you have seen thread re "81" Coureur:

Not sure what that decal at bottom of seat tube is. The gold decal pictured below was often seen in this era but top shape is different and your decal has letters "ycl" at bottom right. Might suggest it is the retailer's decal? Other decals are available through H Lloyd's.
So... model must be one or other of above. Perhaps better pics of dropouts esp rear drive side and lug work might help. Is seat post size 26.4 to reflect plain gauge tubing? Coureur had "close clearances" with 27" rims - what does frame look like with wheels? What is wheelbase (altho perhaps thrown off by non original fork rake)?
The front fork being replaced suggest a significant collision. Note hole in left seat stay from tire rub. Oh,oh! Also drive side rear dropout seems opened up, distorted? Frame certainly appears to have been "around the block". Wonder what you plan? Might be a good idea to have someone in the know check it out before restoring.
