the auxiliary pitot tube is wrong too. (must be shorter). I'm not sure about Charly's PFMs but the east germans had protection plates on both sides (retrofitted). Same about the mirror (periscope). The PFM had no mirror from factory, but the canopy could be exchanged between MF and PFM, so it could have one. Due to the lack of mirror heating (available from MF) in the east german air force the opening for the periscope in this case was closed with just a metal plate.
BTW: It's interesting (and confusing) that the east german PFMs were called SPS (or SPS-K with gunpod), as the name PFM was us
