EC360 from manufacturer RFT is an interesting triode with low internal resistance (Ri is approximately 120 Ohm). Nominal plate/anode current is 200 mA and nominal transconductance is 20 mA/V (original datasheet is available for download). It was used for example in DUOSKOP EO2/131 and several medical devices. All of the available tubes are completely tested with RoeTest V10. New in box, boxes do wear some longer storage marks (please look at the gallery pictures).
