What is the value of a 38 WCF Winchester Model 1873 lever action rifle?

Only as much as a buyer is willing to pay for it. :-)

OK, more information is needed, as many aspects widely effect the value. Metal condition, wood condition, bore condition, fit and function, has it ever been restored, year of manufacture, and type (takedown, saddle ring carbine)

I've been searching for one for years for under $750, and haven't found one yet as, even in fair condition, I'll rarely see them for less than $1000. Typical, good-condition models go for $1400~$2000, with prime condition models easily doubling or tripling that.
