Thank you for your question! The Museum cannot offer values or appraisals due to our non-profit status, but there are collectors' books and magazine articles that may be of interest to you in the Library collection. I'm listing a few below. The Library also has historical information on Pyrex insulators.
You could also contact one of the collector's groups for insulators, such as Crown Jewels of the Wire. They publish a newsletter, where some of the articles listed below appear. These groups typically do a lot of research on numbers, marks, dates, etc. and could save you some leg-work!
