I go more for the firefighting collectibles.. I have a bunch of street signs, novelty signs, old extinguishers, cast iron fire engines, code 3 collectibles, Faraday alarms, a Federal Signal Gas siren (well the casing anyway, the motor never worked), Emergency "51" Helmet, books on various fire engine manufacturers, histories of firefighting and the like items. However, I do like old EMS stuff, resuscitators, empty cases that things came in, various lots of supplies, the old green hudson oxygen boxes, Erickson & Johnstone resuscitators, Emerson resuscitators, books on the subject of EMS history, Cadillac ambos, Cotner-Bevington ambos, Pontiac ambos. I also have several DVD collections of films that are about EMS, rescue squads and firefighting; and I own the "James O. Page Collection". I take the stuff to flea markets, etc, and trade it for firefighting stuff. It's the hobby side of emergency services.
