We have historical information on Pyrex insulators. Are you able to visit the library to look at these? If so, we are open 9-5, Monday-Sunday and have a reference librarian during those hours to assist with research.  The Museum cannot offer values or appraisals due to our non-profit status, but there are collectors' books and magazines that may be of interest to you. I'm listing a few below, but maybe even more productive would be to contact one of the collector's groups for insulators, such as Crown Jewels of the Wire. They publish a newsletter, where, for instance, this article on Pyrex carnival glass insulators appeared:

These groups typically do a lot of research on numbers, marks, dates, etc. and could save you some leg-work! If you do want to come in, let me know and I can pull some materials in advance of your visit.  Hope this helps!
