Yes, it does.

Lens now sold- thanks for interest.
For the record, it was checked over prior to sale by a photographic technician who concluded that although there was some dust inside the lens, it was not such as to detract from its its optical quality or its value.

For clarification re the 3 small blemishes behind the front element- a pretty experienced camera buff has had a look at the lens for me and has expressed the view that it seems to be dust. But as he is neither in the trade nor technically an expert, he won’t let me rely on his opinion in case there is any subsequent controversy.
So, as it seems likely to be dust, I then asked John Riley what the significance of dust inside the lens was, and I quote his reply: "most lenses have a bit of dust inside and provided it isn't excessive it doesn't have any optical effect”. He does however want to make it clear that he has not seen the lens in question, and that that is just a general comment by him.
