Have you run out of packing material again? Surely popcorn was cheaper

I will try and get you a nippon kogaku shirt if I can

Does this 100/2.8 Series E have the all-plastic helicoid threads? 
>>>Does anyone know which, if any, of the Series E lenses do not have plastic helicoids?<<<
The 28s.E and the 35s.E interest me, but I'm hesitant to dump even a small amount of money into what is essentially a self-destructing lens.

When I serviced my 28E I did not investigate the helicoid, but my 50E has a plastic helicoid.  I suspect the 28E has plastic helicoid as well.



I have a 35E sitting around, the former owner bumped it and the helicoid has mis-threaded.
