Variometer Installation for T-16

[horsa]

Long shot I know but does anyone have a manual reference or photos of a Wireless No. 19 mounted correctly inside a T-16?

Installation of the main set and power supply is the same as found on a Windsor Carrier with the P/S Unit straped down sideways on top of the wireless. A Crystal Calibrator can be mounted to the upper exposed side of the P/S Unit. The Control Box bolts directly to the armor that is between the driver and the wireless.

Question is, where does the variometer bolt to for this vehicle? The wireless and P/S Unit have no accessible mounting holes for the variometer plate in this configuration. And the vehicle hull shows no existing or filled in holes that would indicate a location for the variometer. Aerial mounting and control box holes were pre-drilled on each side of the vehicle at the factory for all T-16s which is why I would guess the variometer mount didn't bolt to the vehicle in this case.
