Two incredibly interesting images appeared on PixPast (the web page for a collection of colour slides from the 30s-40s). They show two TauchPzs from 3.Pz.Div. The first one shows vehicle 1231 (p100 & possibly 97 of TauchPz supplement) during the early stages of Barbarossa. It shows first clear evidence of the jack block moved to the rear because of a spare wheel placement. Note the soot from the unmuffled (is that a word?) exhaust.
The second image show another TauchPz from the 12th Kompanie but much later in 41 when it has been transferred to the 8th K. I know of a rear image of the same situation that clearly shows a hurried reapplication of numbers.
In front of the new turret number "812" is a small marking which may be the rearing Berlin bear on a yellow shield. Although it is does not seem to appear on 3.Pz.Div vehicles until 42.
PixPast - A great find and now a regular visiting place
