As I was going through the materials for documenting the L420/L520 on thinkwiki I noticed references to an L410, L510, and L421 in the hardware maintenance manuals. None of these models appear in the tabook or the ltwbook so I can't find much about them. Does anyone know if they actually exist or anything about them?

I did also find this ebay listing: http://cgi.ebay.com/NEW-ThinkPad-L510-L ... 3a67d38692

Config 2873-A25 does show up as an L510 on Lenovo's site and browsing the products on the support site does show other L410, L510, and L421s.
