I have a copy of Iron, Blood, Snow & Mud by Phalanx games.
I added Axis & Allies pieces and control markers to replace card tokens that came with the game. Have not played it, ironically. Just have too many games.
I saw that you were maybe looking for the pacific 2nd edition board. I have an extra board. The corners are a bit bent. They came that way and i complained to Wizards and they sent me a new board. Trade perhaps?
––If you should end up with a surplus of the “cardboard airbase markers” I would be interested in buying them from you. And you can almost always find some A&A-Guadalcanal games on Ebay, just wait for some at your right price.
Good luck finding any set 1 boats or planes cheap. Most things in that set go for $5 and up. I just sold a complete set 1 on Ebay and got $450. Most rares average $20 and up, hell most Planes are $10 and up, even little Destroyers are going for 3-5 dollars each
