Coal forge reference book?

[zampilot]

Is there anything out there to forges as Anvils In America is to anvils, addressing coal/charcoal history of commercial manufacturing in the USA, say from 1800 on?

I'd guess that there were several thousand makers as pretty much every small foundry would have done some as requested and small foundries were *everywhere* 100+ years ago. Also very hard to date them as foundries tended to use the mold boards once made practically forever. Not unusual to see items with a patent date 50 years earlier than the date they were cast!
