Hi Jeffrey,
In the Wiki article that you quote there is this statement:
"In the late 1930s and 1940s, Corning also introduced other products under the Pyrex brand, including opaque tempered soda-lime glass for bowls and bakeware,"
I am suggesting that only the blown tubes might be soda-lime.
The tube that Charlie is working with in the photograph has the separate moulded face plate and
I would therefor expect it to be of borosilicate glass and PYREX as we generally understand it.
I think your own 702 is a fairly early model. Do you know whether it has the later moulded or the earlier blown type of CRT?
