To my knowledge, the Lamy 2000 line has had the following models:
Fountain pen (released in 1966, minimal design changes since then)
0.5mm mechanical pencil
0.7mm mechanical pencil
I'm wondering if these "standard" editions were released at the same time in '66 -- probably not. Did the rollerball really come out in 1966? I'd believe the ballpoint did, but that seems very early to have a top-notch rollerball. Same with the mechanical pencils--when were they released, and were the different lead sizes released at the same time?
It seems that the limited edition 2000 models are more of a recent phenomenon, starting with the blackwood ballpoint released in 1996
Blackwood ballpoint (1996, 30 year anniversary of the Lamy 2000 line)
Limited Edition fountain pen (2000, namesake limited edition)
Ceramicon ballpoint (2006, 40th anniversary edition)
Taxus ballpoint (date?, any significance here other than material?)
Titanium ballpoint (2009 limited edition, any significance here other than material?)
I'm also wondering if there are "tell-tale" signs to dating certain 2000 models. Obviously the W. Germany imprints are one indicator of a date range, but that's not very specific. For example, I read somewhere that early 2000 models had an "L" stamped near the piston (I'm assuming "L" for Lamy). Or, I noticed that my W. Germany mechanical pencil has slight difference in the mechanism as compared to the one posted in Dillon Ang's review of a more recent L2K MP. Also, the clip is slightly different (the older model doesn't have a Lamy imprint on the clip) and there is no indication of lead size on the older model. Obviously these changes are iterative, but there's got to be some record of when the production changed.
Haywoody has done an excellent job sussing out information on the Lamy Safari in this thread. I'm equally curious about divining more on the Lamy 2000 range. I suppose one fun thing would be to hop on a plane to Heidelberg to see a friend there and tour the factory -- or to snatch up old, crusty 2000s that pop up on Ebay. In the meantime, any information or links you'd care to share would be most appreciated.
