Bertram 46 gauges question

[Navatech]

There are 6 holes in the step leading into the salon (coming from the cockpit)... 3 to the left and 3 to the right... Presumably one set per engine...

In 3 of these holes are the remains of gauges... 2 engine (coolant) temperature gauges (mechanical) and one so far gone I can't make out what it was...

Does anybody know what gauges were located in these holes?!...

Chris came through (once again) and sent me a few pictures by Whatsup... Just in case somebody finds this thread in the future I'll post the answer:







Engine temp, engine oil pressure, gear oil pressure...
