Glen, Nope Criterion's spine numbers just represent the order in which they where released. I know of a few Criterion Ld collectors whom are working on the entire set. The number just gives them something to check off on their list. Honestly other than Criterion I wouldn't get critical as far as spine info. Just be sure to mention if it is full or widescreen, what the aspect is, letterboxed, dolby digital, dts etc... This reminds me I have a second Pioneer Laserdisc player in the bedroom I should sell! I may need a check-list to rememeber all the unused equipment I have. Good Luck with your auctions!
P.S. Screws would work much better, than swinging a Hammer inside your head! Unless your partial to nails, then I would recommend a Nail Gun? ;0)~
