Hi here are some photos of a recent acquisition/fettle. This is an AB BAHCO Primus No.100/4128 made in 1959. The box is of course a later addition, and the Optimus windshield was added to allow me to brew-up outdoors on a breezy day: The stove performs faultlessly and easily passed the "Tea Test". The Primus No.100 is a much better and more powerful stove when fitted with the tubed Primus #4128 roarer burner than it is with the original "lipstick" burner of this model. Best Regards, Kerophile.
