Type of EGT Probe?

[Bob Waters]

My '62 -250 (sn. 3110) is due for another EGT probe, but I'm not sure of the type to get. The lead wires appear to be red and grey, both up-stream and down-stream of the connections. According to Spruce, Type K is red and yellow and Type E is red and brown - no red and grey found. I'm not ready to upgrade - just want to go back with what I have. I'd appreciate someone telling me what I have!! Thanks, Bob
