Oiler Value

[JimF4M1s (Deceased)]

Some areas of the country have different price ranges. In my area:

The IS oiler in near new condition is worth between $10-15

The IU oiler used, depending on condition, is worth $25-40

I would keep the IU even if you do not have an Underwood gun. You could trade it for one that goes with your gun. The IS is common, goes with any gun.
