New old stock #24 (19/36) PTFE (Teflon) insulated  stranded, silver plated copper hook up wire, color White/brown/green, weight 1# 12 oz on spool, surplus stock, 100% New and Unused on a partial Factory Spool, from Watkins-Johnson who built equipment for the government. I estimate about 500 feet based on wire charts.  I love this stuff, and use PTFE Teflon wire for all my projects. Cheaper than a lot of the other wire vendors on eBay.
