Ever get the feeling that vintage Lamy had more to offer than the 2000 and cp1? The design 20 series was an attempt to make pens for a younger audience in the 1970s, and I think of it as the link between the start of the modern 2000 era and the plastic appeal of the 80s Safari era.
I started with the Model 125 pencil. Very nice construction with hairline steel lower for stability and a black 2000-style textured plastic upper. The 0.5mm tip is a slide pipe and the click feels nice, if a bit muted.
I found the model 225 ballpoint later and it comes in a glossy mustard yellow top. The refill is a standard, unloved M16. Nice clicker action, just a touch lighter than most Jotters.
Some day I hope to find more colors of the 125 and 225…
