I've been working on a reference sheet much like the standard US armory for the Alchemist's potions from the US games and for the European weapons. I've added some new weapons to the set as well, with some base rules for pricing and use. You can view and download it here: (click)
You click the link above, view the full-res image in photobucket, download it, and then print it on A3 (or split it in half and print on 2x A4). Just use the original size, or stretch it so it fits the page. Use minimal margins.
I've printed it on A3, folded it, and laminated it :)
