Not now there isn't. Somebody has bought it !

Canons go BANG! don't they?

All Meyer/Pentacon 135s will show what looks like 'something wrong' around the inside, just beneath the front element. There is a thin brass shim in there, the appearance of which gets slightly distorted because it is so close to the edge of the glass element. What is on the images here looks a bit excessive however. Without handling it I cannot comment further.
If the seller is a reputable Ebayer (like me) you should be offered a refund straightaway. Contact the seller privately first (don't just open a case or use the 'item not as described' option - which opens a case!!) and try to resolve it amicably. If you get told where to go, then you open a case, but it should never get that far.
(edited in)... You seem to want it not to be 'a bum'. If you really want to keep it, carefully unscrew the front ring and clean the front element, which comes out very readily (make sure it goes back in the right way up). At the same time, you can check that brass ring - which does go greenish like your photo - it's brass! Unscrew the conical rear mount and you can then do exactly the same with the rear element (which can be further dismantled ito two halves). The only risk you take doing this is slipping and scratching the glass. Otherwise it's very easy and foolproof. Message me if you want to know more.

If you are doing portraits then an old Russian 135mm will be relatively cheap and will give amazing results. In particular, the Jupiter 11A, which is a superb lens. The A suffix on Russian lenses means it has a T mount (usually M42) so that can be changed for a Pentax K if you like. If you like bokeh you'll get it in spades with a Meyer Optik/ Pentacon f2.8 135mm. Best thing is to buy them and try them. 9 out of 10 can be resold for what you paid for them.

You're just being unkind to me !

My istDS would discharge a set of batteries overnight if I left them in. I tried every sort of battery in existence. Finally I decided it had to be the contacts, so I looked and found that those on the door had been compressed over the years and hardly exerted any pressure at all on the battery ends. I pried them outwards so that there was resistance when I closed the door. No further problems.

Beautifully done.

I've just failed for the umpteenth time to get airborne in a hot air balloon. (too gusty) I've been booking it and having it cancelled for four years now ! They've even upgraded me to an 'anytime' ticket to try and get rid of me.

Ah, I see (?) you were wearing your writing/ typing glasses then?

SHE deserves an award, never mind you. That is some feat of creativity.
