Hi,

Did you remove the thin threaded ring (not in the pictured in Mick Feuerbachers description) that holds the name plate in place? If you have, the name plate ought to fall out without resistance. It does on my two S2s. If it doesn't, maybe the meter wires are stuck between the name plate and the front element (or the lens housing). I would try to drag it out by "suitable force". Expect the meter wires to break near the solder joints. They did on my two S2s
