In fact, an inertia starter I believe : the handle don't directly drive the crankshaft, but a set of multiplier gears which turns a flywheel faster and faster, subsequently engaged on the engine.

It is an inertia starter, it does drive a flywheel through gears at high rpm. The usual technique is to wind the flywheel to full speed (about 2 rev/sec on the handle, 18,000 rpm on the flywheel) and then remove the starting handle and engage the starter drive dog which drives the crankshaft directly and rotates the engine.
However, it is possible to continue winding the handle when the starter is engaged, and in this case the handles are driving the crankshaft directly, through the flywheel drive. This is not really necessary and only helps a little in some difficult starting conditions, but it is seen on some film of original engine starting.

Camo notice text on wheel well 2nd word?

As Engineman has said, and the colour of the fluid as well. Colour is an important distinction in aircraft servicing, especially when different fluids and greases are used in different applications. Oleos are pressurised with fluid (and nitrogen), so it is important to make sure the right fluid is used.
 

Yes, the Germans did have a bit of a mixture of fluids colour id, names and codes. Here the Violett brake fluid has the term, "Druck-Flüssigkeit Violett" ( Pressure Liquid Violet) but no number code in the Bf 109 manual.
At the same document, Violet is referred to as "Fl.Drucköl* " with the asterisk and a note at the bottom of the table, wheras, the normal "Fl.Drucköl" is "Fl.Drucköl rot" (red).

So, IMO, it is no surprise that they had cock-ups, often they just use the abbreviation! The different oils are incompatible with certain types of seals, a common issue with hydraulic systems.
