Which fill probe for BSA Ultra MMC

[springfieldm6]

Hi
Does anyone know which fill probe is used for a BSA Ultra - it’s one of the early Birmingham MMC models, rather than the current model.

I think they're a generic brass probe

There are two different BSA probes

Ours is Black steel. Can measure if need be.
