Price of Glory (Iron Ivan) Errata and extras?

[DaveCrow]

Long ago in the days of Yahoo Groups there were files posted giving errata and expanded platoon rosters, vehicles, etc for Price of Glory.  My copies are gone multiple hard drives ago.

Does anyone know if these are available anywhere? I am picking up Great War gaming again after some time away. I found the files useful back in the day.  I see Rattrap Productions are now selling the rules in print and pdf, does anyone know if the expanded information is included in their version of the rulebook?  I have two copies of the original book.
