Spoke and rim induced punctures on Brompton


I've had a Brompton for about two years, its a 2012 model 3 speed S,raw lacquer. The problem I have found with it is punctures but from the inside of the rim ( it's got Schwalbe Marathons on. I've had about 4. The first three, rear wheel, punctures were soon after I got the bike, I replaced the rim tape, tubes and a few of the longer spokes. I've just discovered an inside puncture on the front. Can't see a protruding spoke and the rim tape is fine.

Any ideas? ( apart from a new set of wheels)

I take it the tyre pressures are high enough to rule out pinch punctures.
