Wireing of a 10BP4

I was given a 10BP4 today that appeared to be dead. No heater no emissions.

I resoldered the pins and got the heater to show some life but still no emissions.

I removed the cap to do a little further cleaning but as I looked at the CRT I could see that the CRT is not numbered is the same way as the cap. What would seem to be wire 10 on the CRT is cut off and wire 9 (grid #2) is soldered into pin 10 on the cap.

Is this the correct wireing, wire 9 into pin 10?

If the heater is working shouldn't I expect to see a least a small amount of emissions or is it possible to have a working heater and no emissions? My tester doesn't indicate any shorts.

Thanks
