I think that I-16 had not any fixed undercarriage, but the severe winter condition (snwo+ frost+vry rudimentary airfiled tools" makes in these I-16 unfixed into fixed undercarriage. This is also in the typ 5. Second undercarriage was in I-16 hidden, lowered manualy by pilot - the next factor of making this carriage as a fixed one.
Hmmm...
So these are untrue:

I-16 typ 10 with retractable skies
In the end of 1937 the I-16 Type 10 with increased firepower replaced 5/6 series on the production line, after the Spanish and Chinese combat experience revealed insufficient armament of the I-16. The Type 10 also had new improved M-25V engine and additional 8mm armour plate behind the headrest. This armour was sufficient to stop 12.7mm shells. For winter operation retractable ski gear was fitted (all earlier I-16's had to use fixed ski gear).

I-16 typ 6 with fixed skies
4.7 Ski landing gear
As the reader doubtless recalls the very earliest flights of the I-16 prototype were made with ski landing gear. In Russia this was a "must have" if one wanted to operate a military aircraft during winter campaigns from primitive front-line airfields. Up to the appearance of the type 10 the landing gear was simply locked in place, the wheels replaced by skis and the wheel wells were usually left open (this is not always the case, it seem as if landing gear doors were sometimes detached from the landing gear itself and used to blank off the wheel wells). The front and rear end of the skis were then attached to he wings and fuselage by means of elastic cable fittings. The landing gear could obviously not be retracted. It was only later that retractable ski gears were developed. These began to appear on various types of the I-16 after the winter war. When provision was made for retractable skis the lowest two exhaust were rerouted to the exhaust ports above them. Where the lowest two exhaust ports had been before there was now a bulge in the cowling to accommodate the tip of the skis. This arrangement became standard on all later types of the I-16 form the later type 10 aircraft and was doubtless retrofitted to earlier types.

It makes no sens to use I-16 typ 5 or typ 10 or later typ 18, typ 24 in one combat unit. The difference in speed among these types were to great that whole formation could not sustain the formation. The same you have in other squadrons I do not see the same staffelen with mixed Me 109 E-7 and F-2 or squadron with Spitfire Mk 1 and Mk 2 or Mk 5. So when you have one baisci unit (in IAP escadrila th whole has one typ of I-16.
but didn't the 68.OIAP (already) fly with two totally differnet types (I-16 & I-153 ?)

Maybe the same reason as Richthofen & co

Or maybe the planes were painted as reported

I too believe that the Soviet airstrip was on open space, but they sure had both possibilities and reasons to repair and overhaul their planes indoors.

From paint factory ? (I believe that there was enough red(?) paint at USSR at those days)

I think that the "guard" status was not in use during the Winter War.
Finnish sources mention (special) aerobatic skills of 68.OIAP
