Location of Variometer on a late Ram Kangaroo?

[Bruce Parker (RIP)]

Can you post a picture of the stowage diagram of the Kangaroo you are trying to depict? From that, I can tell you if it is under the A Aerial base or elsewhere. There were two ways of mounting the variometer, one was directly on the inside of the turret/hull roof under the aerial base; the other remotely with a cable lead.
