Dave As W7TFO correctly pointed out, Fischer was a long time diathermy machine manufacturer. Like others, they had their own OEM part numbers printed on their tubes, made by other companies. My Aloe "Short Wave Unit" diathermy device has Amperex A11 triodes in it though. They have shorter plates than the Fischer tube you pictured, must be lower power.
