I recently obtained an early model Noctilux (E58) from another RFFer and upon visual inspection I noticed that there appear to be two holes in the barrel that may be missing screws.
I'm not too concerned with the overall cosmetics of the lens as I intend to put it to work... but a few potential screws missing concerns me... God forbid anything comes loose and falls off while I'm out and about.
The first missing screw hole (yeah I went there) is a large one at the bottom of the barrel right under the engraved "LENS MADE IN CANADA". I poked it with a toothpick and some black-ish stuff that looked like axle grease came out with the toothpick. Is this normal? Is this some sort of lubrication reservoir
The other missing screw hole in question is smaller and is located just to the right of the red mounting dot. I poked this one with a toothpick and some black grime came out. I'm pretty sure I felt internal threads on it too. Is this one normal too?
I've also seen pictures of other noctiluxes with screws missing where mine has screws. Do these things just periodically shed screws?
Your input is much appreciated.
