In my hand I have a HP-35 Red Dot, that has the label "DR. ROBERT J.GLASER" instead of the common "HEWLETT*PACKARD".
Since my last meeting here in Allschwil I have new knowledge. There must have been three typs of Red Dots. The first was the common serie, the second was made for a (unknown to me) company (maybe they have a sign?) and third there was a release for special people that helped developing the HP-35. These units were produced for the 5th anniversary of the HP-35. I think, these units were labeled individualy for the customers. So, Robert J. Glaser must be on of the developer of the HP-35. Does someone of you knows more about this person or the three typs of Red Dots?
Yours
Matthias
