A friend of mine is looking for Butler Creek Flip up covers for a Zeiss Victory 2.5x10 with a 50mm objective. Looking for the correct eyepeice and objective covers. Anyone have that information? I have have been given the numbers 13 for the eyepiece, and 40 for the objective, but it seems that the fast focus eyepiece might need a bigger size, and the objective might need a smallers size, as in 14eye/39 objective.

Trying to save the hassle of having a wrong set of covers, and having to send them back.

Thank you..\

Best just to measure them yourself and match them up with one of the charts displayed on the many web sites or post your measurements here.
