Vic, Yes, it is that T7, and you have the current winding ratio. Some of the earlier K2s used a 13 to 4 turns ratio - I am not certain when the cut-over was made, but I believe it was in the low 1000 SN range. Many of these early K2s have already been changed - I have done several myself while doing repairs or upgrades.
