Now I’ve considered this and it was actually my first thought. I live next to a university and the L (if it's even an L) font looks a bit like the L in the university logo.
I've talked to some people who study there and nobody recognized the symbol. I emailed the university yesterday and asked them if they recognized the logo but they haven’t returned to me yet.

Now I’m not sure about that. It's definitely not hand drawn. In person the symbol look almost burnt in, you can tell that the plastic was melted around the logo indentation. The fact that it's both stamped with a hot enough stamp to melt the plastic and probably painted at the same time, it seems to me that there must have been some sort of relatively advanced tool involved.

Yes actually there was. An old membrane keyboard, no stamp on that one though.

Very interesting. It's not that far-fetched that it actually says ISW in the logo itself.
I sent them an email and asked if they knew anything about the logo.
