You are looking at 2 rolls of Packard Automotive cable from the 1950s. The one spool is Tr. # 56. It is 10 gauge and has an orange fiber coating. It appears to still have half the wire so 30’ to 50’ left. The other is Tr. # 440. It is 7mm and is incased in black rubber. It appears to still have one quarter of the wire so 20’ to 30’ left. Original, unused wire from back in the day.
