Two weeks ago I acquired my first Esterbrook "Bell System Property" fountain pen. This black pen is 5" long and is the slimmer model. [Did Esterbrook make for Bell the fatter one too?]

Unlike my other vintage Esterbrook pens, there's no "Esterbrook" written in cursive. I suppose Bell asked Esterbrook to leave off the cursive "Esterbrook". Correct?
