Re: 1917 eddystone
Pictures would be needed for anyone to be very specific about values, rdecator. The general rule is that when a military rifle has been sporterized, it has value only as a shooter, not as a collector's item.
That makes it depend on how well the work was done, what shape it is in, and so on. Without pictures, somebody here may be able to give you a ballpark estimate on value, but it will be a pretty broad ballpark.
