Replying to my own thread.
Normally I am in favor of logging the scenarios literally. If the scenario calls for 47mm (it) in the Australian OOB it should be reflected as such, with an Italian piece.
When it comes to proxy units, where the special rules actually say use X counter to represent Y unit instead, I could go either way. I just prefer that whatever way we go, we be consistent with.
I know Peter and I discussed a similar issue in the past with Arctic Front's (and LoF) proxy T-34/85 units, where they similarly are treated differently in different library entries, but I don't think we ever reached an understanding on what we were talking about there and I dropped it.
I'm probably the only crabby person who cares though.
