Three 6BM8 tubes. All three tubes are from the manufacturer "Silvania" and are sharp, each with its original box. All three have been tested and confirmed to work in a radio. The two tubes on the left in the first photo have the model number and "JAPAN" written in small letters at the base of the pins. (Photo 5) This is a characteristic of Hitachi, so they may be Hitachi OEM. The single tube on the right in the first photo also has "JAPAN" written on it (Photo 6), but the font is different, so it's difficult to definitively say it's a Hitachi OEM. Will be sent via Nekopos (a Japanese delivery service).
