Thanks! Yes I did check that out. The Citizen is also a different length - not significant. A couple of them have straight barrels rather than tapered. I believe most - all - of the Jr series utilize the 12.5 mm &10.5 mm drill bits, etc, etc. As it turns out some are fancier/more gaudy in embellishments than others. The Jr Milton has cross-hatching on finials & center band. But when you look at a Jr George & a current Jr Gent they look identical in pictures - I currently have neither. The Jr George comes in more different finishes, and can be had in fountain pen, etc. But - when it comes to Chrome finish roller ball, the Jr George is a few dollars more. I wonder why? Might be overthinking this thing, but if I'm going to buy maybe 50 of the kits, that difference translates to real cash - for me at least. Again, Thanks
