A guy I know from a coin collecting forum heard that I was into insulators and he is offering the following:

Standard 1 1/8 dia. threaded pins, unused. Minimum 50 pieces - $4.50 each + shipping. Have around 500 total. Larger quantities available for pickup in central Arkansas. Prefer to deal in bulk.../

Ideally, he would prefer selling in one lot if someone lives nearby. He also has hundreds of common insulators, those would be pick-up only. I personally have not seen them.

Reply to me if interested & I'll supply his contact info.
