2001 Palermo Inner door / Bits missing ?

Not the same motorhome but the door looks like the one fitted to our Rienza. Ours has a fly screen hinged on the door that can be closed leaving the main door fastened back for ventilation. The only snag with it being the blind on the door window can’t be opened without first un latching the fly screen. We leave the blind closed. That’s maybe why yours is missing.
