Here ya' are Andy. Here are some War Time pix of the Sd.Kfz 7/1 . I failed to catalouge the dates of these pix so please forgive me
You can see that at least the Later War time pix are of the Armored version. I agree with LAURA in that it seems unlikely that any UN-Armored 7/1 would have made it through til th end, especially on the Eastern Front , Where they were losing Armor & Material at an Alarming rate. More than likely these later 7/1 were field Mod'd. & on an Earlier Chassis. Being the Later ones came from the Factory already Armored. At least here you get a chance to see them & that later in the War Th Germans , more than likely Cobbled together some Armor for their less-Armored 7/1.
If you do want to do a later war 7/1 I would suggest getting Dragon's Later 7/2 & replace the 37mm with the Flak-vierling, but I'm sure that's a Model for another time !!
This is a favorite of mine b/c it has a Cool camo scheme & can you spot the Camera guy Filming ?
This one is interesting b/c it does not have the Front Armor shields !
No doubt a Flak Battery as evidence of the other Flak-vierling in the background !
A later Up-Armored version of the 7/1
IIRC this is taken on the Western front as it rolls through Belgium
We see this 7/1 Up-Armored & dug in on the Eastern Front !
Hope this helps I'm sorry I don't have specific data for you on When & how long the 7/1 lasted in Service. You could always read Unit History's but of the Ones that I have & have read they are not very specific on the Exact Type , beit a 7/1 or 7/2
