Great idea.  He can clean it up and coat it.  I remember his coating price
was $125 for single elements.
Let me know how it works out.
 
I can see you got to Marc with your Elmar comment.  He gets easily ruffled
when it comes to what he owns.
One time I explained that a source indicated there was a 6-element 2.8 lens
for the Rollei that was in only a few cameras.
He went nuts! A week's worth of rebuttals, etc.  I had heard it from a
repairman who was trained in Germany.
He was an elderly gent so perhaps he did not remember clearly, but you can
imagine what Marc was like when all this came out.

Peter,

I need to give Mr. Stelten a call.  I have a pristine un-coated 
Summar, with faint fogging.  I was thinking of getting it cleaned by
JVS or DAG. Maybe I can get it coated, by JVS.  It might cost
quite a bit, but it might be worth it.

Jay, et al, 

John Van Stelten recoated a Xenotar 2.8 for me. Very very good job. 
One thing to note, it is single coated but is a different coating than 
that originally designated for the glass. The result is a slight color 
shift you will see on transparencies.
