Welcome to the forum EGreis. The Ithaca you are thinking about buying is a Flues model built in 1909. From your description, we don't know what grade it is, so it would be impossible to provide a value estimate. Pictures of both guns would help a great deal. Also, it is unclear what you mean when you say the safety is very worn on the 16 ga. Fox model B. Does this mean the gun can be fired with the safety on, or does it mean that the bluing is worn off the safety?
Other than that, both sound like well used shooters. But without photos of the guns, it would be hard to know what they are worth, or whether they need work, or if refinishing would be a worthwhile option. A good way to get an idea of the value is to just watch the same guns in identical gauge and overall condition on Gunbroker or some of the other firearm auction sites. Look at completed sales, and see what they actually sell for to get an idea of what they are worth. The sale price of guns in higher condition, and the reserve or starting price of guns that do not actually sell will tell you nothing about the true market value.
