How do you open a Pentax 110 auto 70mm lens?

Hi. I hope this is the right place to post this.

I've got the 110 auto system and most of its lenses (missing the 18mm), but my 70mm has got some droplets behind the rear element and I need to get it opened to clean it up.

The 50mm and the 24mm both have these notches which I can use with a spanner if I wanted to open any of them, but the 70mm doesn't. It's just a flat ring covering the lens element. How do you turn that thing? I tried several techniques including using a rubber ring but it didn't work. Is it glued?

Hope anyone can help. The lens is mint aside from the droplets and I want to further mintify it for actual use.
