A nice unscathed surviving section of black cloth covered 3 conductor, shielded audio wire. This type of wire was typically used by RCA for broadcast recording, and by other manufacturers of high quality like Lansing (prewar), Jensen, and Collins. 

This section is about 34" long and in good shape. The internal stranded conductors designed for high quality audio .... three insulated wires total..... two are insulated cloth, green/yellow -- the third wire is black, and the outer shielded sheath is also usable for a ground. The individual wires are .12" OD each / internal conductors are high quality stranded and about 16 AWG. 

 Measure first for your use, as it's quite thick, yet moderately flexible still.   The outer dia is about .28", the OD of the stranded internal wire is about .12" each. and about .06 - .08 which is about 16AWG. The overall length is 34" for this piece. Tough to find 3 wire in this surviving length!   

Generally wire like this fell out of production, after WWII, as the ability to synthesize rubbers and PVC, replaced cloth and rayon as wire insulation of choice. In retrospec, it's now considered superior to seek out certain fabric materials of this ilk. Vintage, original fabric wires are often more sonically neutral and more detailed than later production post war, stiffer fast draw copper -- vinyl.  

This vintage wire dating from the late 1930's was carefully reclaimed from vintage braodcast audio equipment. If you need 3 conductors, individually then jump on this section --- most are only two and it's rare to find this configuration. 

 Original wires like this  sell quickly. 

Check my 100% feedback (check over what buyers have to say ... they love vintage wire for it's tone-neutral characteristics and I get allot of repeat customers ) ...always fast shipping, and always safe double box packing !!  

100% happiness assured on all old audio items.
