Before this thread runs completely off the edge, I would just like to state that I have no evidence there were any non-zimmed Ausf A in Italy at all. The stupid drawing in Osprey's Anzio 1944 started this goose-chase by depicting a naked Ausf A in a two page color spread and being familiar with the actual photo, I ran with it. Upon finding the photo in question and realising the Osprey drawing is bogus, I've got no game. The time period is close enough, the shipment of early model Ausf A's are in the right period, but without records of Fgst. Nr. and where they were shipped, one can only hope to find a photo, otherwise this is like trying to prove/disprove God.
Anyways, in the link Jack posted is the photo in question from page 62 of Jentz's Panther Tank. Great news! Now we know what unit it is from! The caption under it in Jentz's book states it was built on or about Oct 1st from the D-Benz factory. Production figures on page 60 state that 50 Ausf A were built at DB prior to this vehicle, since it doesn't have Zim, I highly doubt the previous 50 did either, then there are the other 3 factories outputs as well. So I'm going to say there were at least 50 Ausf A without Zim. The introduction of Zimmerit was scheduled for Sept 7th, but all factories did not start at the same time. Only 3 Ausf A total were completed before Sept of 1943 at all 4 factories, production did not start in earnest until Sept..
Even though the shipment of 76 Panthers to 1/PzRg 4 wasn't until Feb of 44, it still had some Ausf D included, be they rebuilds (probably, since there were so many problems with them ) or new, I don't know, but the Ausf A were early production models, as seen by the initial horizontal jack placement in photos, and other features as well. Besides, Squadron misidentifies this as a Ausf D, which it is not, because we know the Fgst.Nr. is 151951, which can actually be seen in the photo in Jentz's book.
Time to check out Panzerregiment Bäke.... Schweres Panzer-Regiment Bäke was formed on 23 Jan 1944, so just about the same time as the actions in Italy.My guess is if a non-zim Ausf A can show up in Russia at this late date, maybe Italy too? I would like to know how this Ausf A was identified as belonging to Schweres Panzer-Regiment Bäke? I'm not saying it doesn't belong to Bake, I'd just like to know, as it might shed some light as to the rest of the non-zims...however many there actually are. Since Schwere Panzer-Abteilung 503 is part of this unit and I have the Combat History of sPzAbt 503 I'll see if there are any photos or info there...Searching for II/ Panzer regiment 23 isn't yielding much.
