I have a nice copy of the 70s era Dungeon! but it's missing a few pieces to be officially complete:
1 blue pawn 2 green pawns 3 red pawns 4th level giant snake card 5th level black pudding card 5th level giant card 1st level sack of gold value 500 card
It's the 1975 USA printing, Holmes size box, Product Code 1002 as far as I can tell. I have 'want parts' posted on BGG but no luck so far, so I thought I'd mention it here in case anyone has ever thrifted a copy they would be willing to "part out."
Also, a Dungeon! related query. I've found card inventories but no mention of "blanks." I had one green blank in my set. Does anyone know or remember how many blanks it originally came with? I've poked around but can't find a photo of unpunched sheets. Presumably they are very rare.
