Hi,
It is true that the Dunstall Commando front master cylinder was those equal mounted on Honda 750 K1?.
If it is not true, what was it?.
 
Ciao.

The master cylinder on my 810 dunstall looks the same as a K1 Honda, has metric threads, and the seal kit and piston from a K1 are identical and work in it so I would say it is

Another yes from me. I had one some years ago, and I also owned a K1 Honda 750, and the master cylinders were the same.

Please,
Could someone tell me how and where the wires were connected to the electrical installation of the front brake swithc?
That is, where was located the brake switch?
Thanks.

There might not have been any switch?

In the UK at least, at that time, there wouldn't have been any legal requirement to have more than one brake system operate the brake light.

And my US '74 mk2 didn't have the front brake switch factory installed (I just did it this past week end).

If the Dunstall used a Japanese master cylinder of that period then in its OEM fitment it would have had a pressure activated switch in a splitter block between the top and bottom brake lines and most likely bolted to the lower triple clamp.

My 1974 US spec Mk2a has a switch in the usual position in the master cylinder ?
The banjo bolt pressure switches work well also.
