I would like to suggest the Daimler Plattformwagen 28/52 Gepanzert mit 7,7 cm Flak L/27, which was a fully armored turreted AA (and Anti Ground) vehicle produced and tested in 1909-1910 with overall 2 produced.
The armarment is sometimes called up to 3 different designations (57mm, 7,1 cm and 7,7 cm), however, only 7,7 cm existed, the other 2 were publication errors from different older texts, the 7,1 cm caliber never existed, and the 5,7 cm wasnt used for AA purposes, for AA and in such range only existed 7,62 cm, 7,5 cm and 7,7 cm.

And this is one of the multiple different models of 7,7 cm guns.

With the start of the 1900s, the first partly armored cars started to appear from the british (like the Simms War Car), the french (Charron, Girardot & Voigt) around 1902. With the first fully armored cars around 1905, such as the CGV and Austrian Austro Daimler Panzerautomobil. Along these Heinrich Erhardt started development of his own ideas with a usage as AA vehicle in mind. Along others such as Daimler, Krupp and so on.

Which resulted in a series of different Krupp AA guns on different chassis (mostly Daimler Plattformwagen 28/52) in different versions, with armor and without and different armarments.

For complete protection and usage as sort of Infantry fighting vehicle these were also reinforced with armor of 5mm (tho also with angles), in a similar fashion as also Erhardt with his 5 cm BaK L/30 vehicle. Was found that armor of only 5mm was rather insufficient as well as with a weight of 8 ton the cross country performance was rather bad. Overall it was not continued in favour of other simpler vehicles such as the KD-I with simply pintel mount and the same gun as well as L/35 guns.

As such later on the armor was also taken off (also photos of) tho i suggest it with sayed armor.
