Letter press type set lead letters (Largo near indian rocks)

I am looking for complete or incomplete sets of lead letters used for letter press type set machines. I am unsure if I'm calling them the correct thing. :) basically these are usually made of lead, brass, sometimes other metals. And have letters numbers or sometimes artwork on them. Sometimes used for heat pressing or newspaper like printing. If you have anything like that I'd be interested in taking a look. I'm in Largo near Indian rocks Beach but may be willing to travel depending on what you have. I thank you for reading this far. :)
