Hello Chris, Nick and Col.,
That is much more detailed information than I expected I could get when I posted my request. So, thank you very much!
I wonder if such a Zaehlwerk and cockpit equipment for launching the V-1 has survived.
The reason why I was asking is that I have a He 111 control wheel that has an unusual button attached to the wheel. So far I failed to find a wartime photo of a He 111 cockpit/wheel that shows this button. Therefore, I thought it could have been used for launching the V-1, but since there were two separate switches that were not attached to the control wheel, it must have had another purpose.
I have published photos of the wheel and button at my website:

Cheers,
