There are a total of 4 tubes: 3 x 12BH7A and 1 x 12BH7. Starting from the left on the first image: * The tube has "12BH7" silk screen printing, without the "A" at the end. The manufacturer is Mazda. * The tube has "H7A" silk screen printing, with the first three characters missing. The manufacturer is also missing, but based on the font characteristics, it can be identified as Matsushita. * The tube's model number silk screen printing is readable, but the manufacturer's silk screen printing is missing (probably Toshiba or NEC?). * The model number silk screen printing is near the base of the pins. The manufacturer's silk screen printing is missing, but because of the "JAPAN" marking, I believe it is Hitachi. I do not have any equipment to use these vacuum tubes at the time of listing, so I have not been able to confirm their operation in a device at the time of listing, but I have confirmed heater continuity. There is no box. I will ship via Nekopos. # 12BH7-A 12B-H7A
