I knew the above from the Hünecke book, but what follows is what really
interested me. Thank you!

Well, so I guess I'd at least have to see and examine one in order to even
try making something like it.

Hm, I was offered one by a list member for $ 15.- incl. shipping. Sounds
like a good deal. If for some reason it should not work out, I'll get back
at you. Hamburg is basically at the other end of Germany from here, but if
they did mail order that might be a very interesting thing - I'm sure the in
focus cord won't be the last Olympus item I'm looking for.
>Hope this helps,
Sure did, thanks again.

It is indeed. :-)
