If you have a copy of Battlefront’s excellent PC game “Combat Mission: Afrika Korps”, the scenario designer includes availability information by month for a fantastic variety of kit that I should think is as accurate as anything. It’s also still a stonking good game in its own right.
Oh yes, that whole series is just fantastic. Had a little difficulty back in the day with the AK game due to PC performance with the dust effect, but the game was smooth with a new PC. I had forgotten about the info supplied. I wish their old forum was still around, so much great info there, as well as excellent skins/camo files. Might still have them all on the ooold PC hard drive. If for nothing else those games were great for having scenario editors and the map maker.
