I am resending this message because it may have disappeared into a black
hole on the first attempt.

Two more responses on "portagraion".  Udai Venedem is a French rare book

Apparently, it is quoted from an old catalogue of instruments, and it
comes just after "drawing Pens". My suggestion is "portagraion" could
mean "Porte-crayon", that is a box to keep various pens. Have a amused
look at

I asked a friend about the portagraion. He thinks that it is a miss-spelling
of the word "porte-crayon". The porte-crayon used to be part of cases of
drawing utensils.
Porte-crayon = holder of drawing material whatever you used in 1745.

Somebody asked me about whether aluminum alloys were used for cigarette
foil.  My recollection is that in the 1960's Anaconda Aluminum sold
cigarette foil in at least three different alloys.  I have no idea what the
alloying elements were and whether lead was one of them.

I would like to point out that anybody who is seriously worried about
radiation would wear not a lead helmet but a lead LOINCLOTH.
