[Bernard nicholson]

Seriously  the Allen screws cant be tightened to the same degree , some of
the collars in this gear really need to be very tight!

I have come across, the ART13 uses them from WW2  , their advantage is that
they have an increased surface area when compared with an Allen Screw, and
consequently can be tightened to a higher tension ,  changing them all at
your radio site to standardize  , would eventually create great confusion
once the radio passed on to  a new owner  which they all eventually will, it
would also take away from its value for the purist collector , in my view
it would be an act of sacrilege even an act of apostasy?  regards Bernie
