You might also consider this adapter. I bought one and found it to work well on my Duaflex III. Checking just now I find that it will fit the Brownie Hawkeye Flash as well.
I would be interested to know what the results of your photos were, when using the adapter.

That adapter most likely will not take care of the synchro time issue connected with all box cameras.
I expected such reply...
And the synchro-switches in box cameras are simple enough for a tinkerer to turn his old plain box into a "synchro-box".
Thus: no excuses.
Due to its character of combustion a flash bulb typically is triggrerd "prematurely" that is before the shutter has completely opened.
The character of the electronic discharge tube however necessitates to be triggered at the start of the completely open period.
This synchronisation is critical for discharge flashes. For combustion flashes how critical that is depends on the kind and location of the shutter, and once effectivity expectations. Thus with the latter there should be room for trial.
The old tinkerer/engineer in me wonders if, given the relatively benign electrical parameters of modern electronic flash trigger circuitry, one could put some sort of passive RC delay circuit in an adapter to add maybe 40 milliseconds delay to firing the flash, letting it work on M sync. I fear there are enough variations in sync timing and flash circuitry it might be unlikely to arrive at a universal fix, but it might work on a case by case basis.
Since my only box camera has no flash, I have no incentive to torment myself any further over the idea!
Now its me who does not get point...
It was just in the old box cameras days that trigger-voltage was quite high. Or do you refer to setting a flash trigger into an otherwise not sufficiently isolated shutter assembly. In this case you are right. I neglected this issue.
The old bulb flashes had enormous currents that synchro-contacts had to withstand, especially when flashes were set up in parallel.Some older flash units couple the capacitor directly to the contact switch in the camera. The high-wattage discharge of the capacitor is enough to fry components rated for low-power.
