What is the value of a Marlin Model 18 pump 22 rifle When would have these been made?

This is a rare little gun, It was produced from 1906 to 1908.There were about 1500 of these made and were offered only with octogan barrell. The value is pretty much up in the air,,if the rifleing is in good condition,if the furniture is in good shape and if no rust or pitting.I think the last time i looked the one i have is worth about 350.00.But i have never seen one on auctionarms or gunbroker so just name your price is the way i see it.
