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.

About the NRG

If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.

The Guild is a non-profit educational organization whose mission is to “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.

The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal. The NRG also publishes plan sets, books and compilations of back issues of the Journal and the former Ships in Scale and Model Ship Builder magazines.
