Identity Ju-52 D-AQUI Speyer

[MainPower]

Not sure where to ask but will try here first;

Does anyone know the "real" identity of the Ju-52 D-AQUI at the Technik Museum Speyer (Speyer Museum of Technology)?

I know there are/where two at Speyer and two at Sinsheim.
But the Speyer website only mentions the one which was salvaged from Norwegian lake Hartigvaansee in 1987.
Also I read the LOG Speyer Technik Museum OCT19 which mentions:
Inside first hall: CA+JY / VB+JA Junkers Ju-52 3m g4e West German Air Force Light grey cs
Inside second hall: D-AQUI CASA CASA 352L Lufthansa metallic cs

I just wonder if this is the T.2B-209 with cn 100 as mention at CASA 352L, T.2B-209 / 100, Technikmuseum Speyer

I have noticed that a lot of planes at the Technik Museum Speyer and Sinsheim have a fake livery and registration...

Thanks,
Matthijs
