Apart from the pun in the name, the Manual of Bronze is a slim below-comic sized volume, a totally unique object printed by Millennium Comics in 1992, during the brief time they had the Doc Savage comics license.
It's worth owning for no other reason than it's intimately researched and complete and shows diagrams of gadgets and equipment like Doc's Helldiver, the Fortress of Solitude, etc. I didn't care for the Supermachine Pistols' out-there design; since the machine pistol later on became a reality in the form of the uzi, wouldn't it stand to reason they'd look something like that, only with a curled magazine?
What's more, this is the only book of its kind thus far made for Doc Savage. Perhaps one day we'll get a more detailed illustrated reference. Until then, this one will have to do.
