My '70 B roadster has a mix of blue vinyl wrapped and cloth wrapped wiring - predominantly vinyl, some cloth in the engine bay and boot. Is this normal - i.e. some cloth stock left over during manufacture and tossed in to deplete stock, or possibly a PO kludge? I'm under the impression that cloth looms were out by 1969. (This car was built in 08/1970, FWIW)
