Could anyone help tell me the years of production for the Tropen Scholar, and what design changes there were?
Lambrou mentions that Tropen sold 150,000 Scholar pens a year from 1945-1948, but doesn't say which year the pen was launched or when Tropen stopped production.
Recently bought these Tropen Scholar pens --
I suspect that they were were made in the last 2 decades, especially since they were sold with the circa-1989 Scholar pens (completely different-looking!). But I don't know how to date them...
