A while back I waxed long on avoiding lead components on models.  The definitive answer to the "lead question" is on page 226 of Vol. II of NRG's Ship Modeler's Shop Notes, which I just received.  The article is an excerpt from the full-length article in Vol. 43 of the NRG Journal. 


The problem is out-gassing of organic acids - primarily acetic acid - from wood, finishes and glues common to model making that attack lead.  Once started, the reaction produces its own acetic acid, in self-perpetuating destruction of the lead.


The oxidation of bullets in cartridge collections I have seen is a direct consequence of displaying/storing the collection in an oaken display or drawer.  In the realm of modeling, bass wood is listed as one of the worst offenders.
