Default Mi-8: Question regarding appearance

Guys,

I've noticed in photos of the Mi-8 that the nose sometimes appears to be rather high up from the ground while parked, and in other shots the nose appears to be level with the ground. Is that a difference in variants, or simply because of the weight difference, e.g. full fuel tanks, etc?

Nose up high (I kinda like that "look"):


Nose level:

Kind of hard to tell from the picture, but doesn't the 1st chopper has its rear shock absorbers fully in? Which would point to a weight difference between the birds I'd guess. Or maybe the rear gear is different altogether, I don't know?

I would think that the first picture is from a museum.
In most aircraft museums they take out the engines so that would explain the difference in weight on the front part of the aircraft.

It's a combination of weight and over- or under-servicing the nitrogen in the nose strut. There is a set pressure for the struts when the aircraft is on jacks, but it seems like many places just do it on the ground, which leads to varying amounts of pressure in the strut. Also, as mentioned, weight on the aircraft will have quite an effect. Where I work, if we can't use jacks for whatever reason, we try to get the nose jack point (next to the strut) approx. 36 inches off the ground when the aircraft is empty except for fuel (maybe half-full of fuel).

My guess: Russian manufacturing tolerances

Is is exactly what I was thinking about. Also I believe the Mi-8 have some Kind of hydraulic System to jack the Heli, doing easy the load cargo

Take a close look at the second picture. The tires are not on the same level, this chopper raises also his nose a bit.
