Not the best reference book. Admittedly I recently bought it for peanuts at a gun show and am pleased with the pictures only. Here are the reference books or authors I suggest- klaus patzwall, Don Boyle, and Antonio scapini. All better than Craig's. Save for Gaspares book on all other tr rings coming this fall. Skull designs vary between ring generations this is true. It is a separate soldered piece, so there will naturally be differences. 30s rings are different than 40s rings, and transitional rings exist with qualities of both. Wear is different based on lots of factors including ring construction, affecting the skulls quite dramatically. Some have even had stones set in the eyes (btw- hap if u read this one day I'm ordering one with the green stones- beautiful man!). Look at a later war ring - I think 44 rings can really look quite amazing and have been often replicated. I do prefer earlier rings, but they wore pretty substantially. Gaspare has seen one dipped in gold I believe?
