Description Technical Specs   Appears that 13D4 preceded 13D5. These have the old style STC logos with BVA stamp. Etched tube type 1571 - one of the 12AU7 codes that was also used for Brimar ECC82 types like CV4003, 12AU7, CV4034 etc. From what we know, Brimar made 3 industrial ECC82 types, 13D4, 13D5 and later 13D8.  From the same lot of Item 1134 - these tubes have imperfect or rubbed off labels and Low Test Scores. Chalky white printing from 1960s is very fragile and comes off easily with contact.
