Dahlmann model issues?

Sorry, can't recall when I bought this. There was a recent eBay listing for something like 50 Euros. I would never pay that much for an aircraft.

In fact, the assembly instructions are in a rather unhelpful diagram. 
Some of the parts are moulded in clear plastic — that makes sense for windows, less so for antenna or propellor shafts, esp. if one is clear and another is beige. There are several clear moulded pieces that could be optional domes for the aircraft, or could be something else.
And to cap things, the Balkenkruz are moulded onto the plane's surface, and don't match the accompanying decals.
Not complaining (much), just totally amazed at how primitive the model is...

but i can feel your pain when parts have different colours... sounds like they wanted to max out on the moulding space, and raised Balkenkreuzes.... i'd say a design flaw
