An Optical " collusion " ?
Do a double check. . . . .
Take note of the gauge of the bare tinned wire size to the right bottom.
Check at the right top corner and see if you don't see the same tinned wire coming out and making a sharp bend to the left and then passing across the top to the left and then passing down inside the unit and coming out as the bottom left bare tinned wire..
To confirm take a DVM and switch into its low ohms function . . .lowest range . . .then short its test leads together.
Observe the reading and then go over and test across your mystery units two wires.
If the unit test the same . . . . as it being a short circuit . . . you have yourself, no ceramic resonator . . . . but a ferrite choke as is used for RFI-EMI supression / filtering.
