Hey, thanks everybody. I found out what the black gunky stuff was. Turns out it was paint. I'm guessing that it started coming off (maybe it melted?) then got under the barrel from use and ended up getting mixed up with what looks like a felt ring under the lens. I got a bit brave after I removed the felt ring, so I took rubbing alcohol to the barrel and it came right off.
It works a lot better now! I'll probably put it up to buy. Doesn't look pretty, but the glass is great.
What do you think?
