Len,

I know. In an earlier post, which I unfortunately left out, I 
mentioned that Leica's mounting and threading wasn't absolutely 
consistent, and that I had two Tele-Elmars with incompatible and 
totally different threads and mounts. The earlier one does not fit 
directly into a 16464 as it should, and has larger diameter threads 
closer to the front (not the coarse ones that connect it to the 
standard focussing mount.

I realize the question is about the Elmar, but Louis was saying that 
what Hoppy had described didn't work for him. I was just illustrating 
that the adapter system didn't always work like the textbook says. 
I've had other instances of this happening. I have a very large 
collection of adapters, and if there's one thing I collect, it's 
adapters :-). Can't ever have too many, and in the end, I'm still 
looking for some (large thread Photar to LTM, for instance).
