Question
Bob,
I have found 2 brown porcelain multi-part insulators and 2 clear pyrex CD 325 insulators.

I was going to just throw them out until someone told me they may be of value and many people collect them.

I was amazed by how many different sizes there are and how many people collect these.

I would like to sell these if possible but do not know any value of either.

I have 4 pictures but can only upload one on here. I will be happy to email you the pictures if you would like

Thanks for your help

Jim

Answer
Hi Jim,

I should be able to help identify and value your pieces.  I did not see a picture attached but the porcelain pieces would be the most critical for pictures as you already identified the CD 325 Pyrex insulators -- These were Corning Pyrex model 401 indicating they are rated for 40,000 Volts.  In clear these typically trade in the $25-$30 range and date from the 1930s.  If you want you can send pictures to my Email address pyrex553@aol.com and I can help more.

         Thanks, --Bob
