So I'm working on a project here, and am confused. A 16200 case tube (acquired as a set along with the gen case) and a 24-603-0 crown ought to be compatible. However the crown simply does not want to push through the tube. I suppose if the O-ring inside the tube were removed, then it'd fit. But with it in place, it's a no go.
Has anyone ever had this problem? I guess there are two possibilities: (1) the crown isn't the right part. It was shown in a 24-603-0 package on EBay, but was sold loose in non-descript packaging. (2) The crown tube isn't genuine. The case/tube/crystal were purchased as a set from roling on Ebay, who is known to have a very good reputation.
*sigh* Any thoughts, ideas, suggestions?
