This looks like a fascinating piece. I'm new to moving legos - any user photos/references of what can be done with it?

You can Google the piece number and there’s a website that will tell you every set it has been included with and you can see the uses of it. I know one set is a drawbridge.

Can this lego piece work with the lego creator tower bridge set

Yes Lego creator and Technic share the same mounting points and shaft splines. Good luck and go create!

Are all the parts made by lego, or are there custom pieces included?

Yes, all parts are made by LEGO. There are no custom piece in this set.

Die Teile selber sind absolut in Ordnung (Lego Qualität eben) aber erst im Nachhinein fiel mir auf, daß der Preis (selbst für Lego Verhältnisse) absurd hoch ist ich meine es sind nur 6 Teile die man z.B. auch Bricklink (auch neu) zu einem Bruchteil des Preises bekommt.
