need a fair price of what it might be worth for an old richland arms 45 cal. black powder rifle with serial no. 2142
200-400 USD
10-1000USD depending on specifics.
$50 to $150 is what I have found on line
Impossible to value a weapon with just the caliber and serial number to any degree of accuracy.
