Coatings Evidence:
During restoration, evidence of previous coatings were discovered as the gun was disassembled.

Original Dunkel Gelb was discovered on the brake shoes and brake back plates when the wheels were removed. The yellow appears quite dull from dirt and age. These areas were also full of sand from a past sand blasting that removed all the earlier coatings but for a few small remnants.

Found under one of the carriage tails:
Original Oliv Grun (Layer #3 in cross-section) or else the later Oliv Grun (Layer #9).
(BOTTOM IMAGE)
This is the underside of the gun cradle or turret. Later Oliv Grun (Layer No. 9) over a Dunkle Gelb (Layer No. 7) over Rot Brun or a red primer (Layer No. 8). As told in the cross section on the previous page, these coatings were applied to the gun in the past after all earlier coatings were removed by sand blasting. That they are under gun cradle tells that the gun was disassembled to some extent for recoating. This work may have been a restoration after the gun was out of service. If a restoration, it followed the original sequence of colors: red primer, yellow, green.
