We know. They were vintages. There were no readily available replicas at the time, outside of maybe the 2.0, but we can visually see it's not one of those. An RPF member also helped production acquire actual Graflexes.
@ BlueSaber: you could possibly be colour blind. Not having a go - just saying it's a possibility. Are you perhaps red-green colour blind?
@SethS thanks so much for your hard work!
I'm always clamouring for more pics - it might be that there'd end up being too manny in the body of the text. Could there perhaps be an "appendix" with a gallery of photos of each sabers (stills from films, promo shots etc) the ones we all pore over to answer questions like "rivets or screws"?
