I sent a copy of my scanned SF 1st ed. counters to Dan. When he will have time to compare them is another matter. I do have some replacement countersheet files, but I suspect they are mid-edition versions. Anyway, the only counter difference I saw between them was the RKKA FLM unit, it has a full strength fire value of 11.
I have some suggested errata for the SS units. I don't know how it relates to the second edition counters.
- Sk7 & SK7/1 should have an armor factor of 0.
- SPW250/7 is not a transport. It should have a self-propelled mortar symbol.
- SPW251/9 is not a recon unit. It should have a self-propelled anti tank symbol. (This makes a difference if one is using the 4th Ed. rules.)
- Also the SPW251/9 combat values are for a SPW251/22. As a SPW251/9 the AT value should be 4-4. (The SPW251/22 did not appear until 1944, so I am pretty safe on this.)
- Marder III units are tank destroyers, and should have the appropriate symbol.
That should hold you until we know what the real changes were.
