It is mis-marked by the store if it says 37-40 on it as the barrels were usually marked 38 WCF. The checkered grips are also a considerable addition to the value of the gun and there aren't many around with the 7 1/2 inch barrel.Aside from target grips there is one local that’s not super nice, has some muzzle wear but it’s a 37-40. - 7.4” and is priced at either 1395 or 1495, can’t recall. This seemed steep to me but I don’t know NS’s. Is that high or inline going on basic description. Think it has the flat latch but didnt ask to have it pulled out of case so haven’t looked too close but rest of seemed all there through case .
New Services in .38-40 were always marked .38 W.C.F. based on my observations of pistols from 1903 to 1937. Still, it wouldn't surprise me if there was an example with something else on the barrel. This is Colt we're talking about here.Sorry, that was my grammar. 38-40-7.5” but I don’t think it had the checkered wood grips and definitely not the fdl’s I would have noticed that.
I have a .38-40 New Service from 1907 (194xx) that is marked 'New Service 38 W.C.F.' on the bbl. I tried to get a picture of the marking but couldn't focus well enough.New Services in .38 WCF were always marked .38-40 based on my observations from 1903 to 1937.

FWIW, Colt did change barrel markings on .44 WCF from CAL. 44 to .44-40 sometime in 1910 between serial numbers 29275 and 29698, if you're interested in trivia like that.
