I swapped the connections as suggested and get the following results - a horizontal deflection/line this time with the line/horizontal coil connections disconnected. I went further and connected the line/horizontal coil connections to the frame/vertical coils.The EHT does not come up as before which appears to rule out the scan coils. So it looks like a dud LOPT. If there are no more tests/checks to try I will open a thread in the wanted section. I feel this set is worth getting going and will try any suggestions.
