Thanks for the reassurance that the lens was probably constructed just as I
expected. The whole job took about 15mins and the hardest part was prying off
the front ring. What tool do you use for that job? There is no little keyhole
in the front ring as I've seen on other lenses so the clearance to get
something under it is pretty tight. I used a dental-pick type tool which was
effective but left some minor cosmetic nicks on the edge of the ring.
Poor quality photos (i was more interested in staying on task than taking
photos) are posted here if anyone cares to see:

Subject: Re: [OM] Cleaning a 12-60mm
I don't have a parts list for that lens, but if it's similar to the
14-54, it's pretty straightforward. Peel up name ring, remove screws
holding front element in. At that point have front element out for as
short a time as possible to prevent other dust from getting in.
