The Victor’s underside periscope is at the Nav Radar’s seat, next to the H2S set, coming out directly below his seat (just in front of and to the right of the nose leg). I’m not sure where it’s controls are, I’ve never seen Lindy’s working.

On the pedestal of the periscope.

It would appear to be the proverbial cuckoo.

I must admit I had expected something American, but sections never lie.
The five figure reference number is certainly pre 60’s.
I can only go on the a/c I worked on 26DK: Lightning 26NA: Bucc 26RA: Jag 26DE: Victor.

XA917, the first production Victor. The nose was used as the crew trainer until the K2s were scrapped.

26R would make it a section and reference number particular to an a/c type.
There has been a list of sections posted here before, anybody?

My dear Robert,
your question was not answered by my post, as you have concluded successfully. Further on, from the fact that I answered a later post, you can conclude that I read your question. So, but I did not reply to your post, which can have following reason:
– I have no clue
– I do not want to answer
Second option hits the nail on its head. I actually don’t see this as question and answer game, with me being the answering machine. As you have access to the internet (otherwise you wouldn’t be here), you can use your own fingers and have the answer to your question right at your command. It is called Google, and would have yielded the answer in less than 10 seconds (just checked).
Now have fun googling it yourself. It is really a no-brainer.

If you were actually half as smart as your mouth you’d be running your department, maybe even the company.
From my answer you can deduce that my opinion of you is very low.

The AIM-54 warhead is only 20kg heavier than that of a Sparrow.

And how heavy is that exactly?
