[Milsurplus] TCS 50 ohm matching unit.

I was wondering if there also is a tuning setting chart for the TCS transmitter output control units vs. frequency when using the 50 ohm coupler because panel controls are dependent upon interaction with the coupler especially when the antenna being matched deviates much from the ideal resistive 50 ohms. The TICS has a front panel paper tuning chart for settings.
Maybe there's a tuning chart, where all (including  controls settings are combined?
The column "EXT LOAD COIL" on the tuning chart could be used and most probably was/is.

I ask because there's a quiet a few control options to adjust when matching an antenna and now one more, using the coupler.

Also, isn't the antenna output connector replaced to match the cable shown in the (Nick England's?) web photo?

BTW does anyone know if my TCS pi-network mod published in Nov.,1960 CQ was ever turned into a field change?
It accomplishes the same function as the coupler, leaves the TCS front panel controls unaltered and only involves the 
addition of a variable capacitor and the removal of the original tank coil.

I ask because, a Marine Corp radio operator/technician wrote and asked if I'd OK his submitting the idea as a field change.
I heard that the idea was used but haven't seen it any where.
