Re: Help
I was thinking it was more like natural corking/aging. The only thing that makes me think otherwise is the fact it's gone up in between the ribs. This seems to be where pests like to do their damage and one of the last places corking takes effect in my experience.
Out of interest, has your friend tried simply scraping it off? I had an Opuntia like this before but the brown stuff was actually more something on top the epidermis that could simply be scraped away if you were gentle.

Re: Help
I would not consider this damage to be due to corking/age - it is still a comparatively young plant, and apart from the damage seems to be growing quite strongly. It definitely has all the hall marks of RSM, which doesn't always restrict itself to the tops of plants.

Re: Help
Could it be the false RSM, as I have similar damage on some loph koehresii & when I was chatting to another grower he reckoned these lophs are prone to damage from false RSM.
It was all over light damage & not as you expect, you normally only see the damage much later after the bugs have moved on.
I only see RSM on succulents as you can sometimes notice the webbing .

on the bottom pic of RSM'd plant corking seems to be coming from the base, so I wouldn't rule it out

Re: Help
It is quite possible that the plant suffered from RSM early on (basal damage), grew out a bit, and was re-infested (top damage) - I've had this with plants in the past.
