Yep, the IN-18's have date stamps. You'll probably pay a little more for those that are date coded in the late 80's early nineties...I think the 'youngest' IN-18's I've seen is 1992 and the oldest 1974. Apart from the Hg doping in the later date codes (no idea when that started), there's really no difference that I can tell...others on this list (Dieter!) will know a lot more about that...
There are some good kits out there for the larger tubes. PM me if you want any recommendations.
